Praise be to Allah.
This is a question which needs a very long answer, but we will summarize it as follows:
Firstly, the names of Allaah are not limited to any specific number. We know some of them and do not know others, as is indicated by the hadeeth of ‘Abd-Allaah ibn Mas’ood (may Allaah be pleased with him), who said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘There is no one among you who, when he is stricken with distress and grief, says, “Allaahumma inni ‘abduka wabnu ‘abdika wabnu amatika naasiyati bi yadika maadin fiyya hukmuka, ‘adlun fiyya qadaa’uka. As’aluka bi kull ismin huwa laka sammayta bihi nafsaka aw allamtahu ahadan min khalqika aw anzaltahu fi kitaabika aw asta’tharta bihi fi ‘ilm il-ghayb ‘indaka an taj’al al-Qur’aana rabee’a qalbi wa noora sadri wa jilaa’a huzni wa dhahaaba hammi [O Allaah, I am Your slave, sone of Your slave and son of Your maidservant, my forelock is in Your hand. Your command over me is forever executed and Your decree over me is just. I ask You by every name belonging to You which You named Yourself with, or You taught to any of Your creation, or revealed in Your Book, or You have preserved in the knowledge of the Unseen with You, that You nmake the Qur’aan the life of my heart and the light of my breast, and a departure for my sorrow and a release for my anxiety]” – but Allaah will remove his distress and his grief, and will give him joy instead…”
(Reported by Imaam Ahmad, 3582; it is a saheeh hadeeth).
Secondly, The names of Allaah are all husnaa [Most Beautiful], as He says (interpretation of the meaning):
“And (all) the Most Beautiful Names belong to Allaah, so call on Him by them, and leave the company of those who belie or deny (or utter impious speech against) His Names. They will be requited for what they used to do.”
The meaning of al-husnaa implies the utmost beauty, and that each name includes the quality of perfection.
Al-‘Allaamah ‘Abd al-Rahmaan ibn Naasir ibn Sa’di (may Allaah have mercy on him) said: Many of the names of Allaah have been mentioned in the Qur’aan, according to the context, but we also need to point out their broader meanings, so we say:
The name Rabb (Lord, Cherisher) is repeated in many aayaat. The Rabb is the One Who guides and cares for all of His slaves by managing their affairs and bestowing different kinds of blessings. In a more specific sense, He cares for and guides His friends (devoted slaves) by reforming and setting straight their hearts and souls and attitudes. For this reason, many of their du’aa’s or prayers to Him address Him by this glorious Name, because they are asking Him for this specific kind of care.
The name Allaah refers to the One Who is adored and worshipped, the One Who possesses the attributes of divinity and to whom all His creation is enslaved. The attributes of divinity with which He describes Himself are the attributes of perfection.
Al-Malik (the Sovereign), al-Maalik (the Possessor), Alladhi lahu’l-Mulk (the One to Whom Dominion belongs). Allaah is the One Who is described with the attributes of sovereignty and dominion, which are the qualities of might and pride, subjugation and control. He is the One Who is in absolute control of creation, Who issues commands and Who rewards or punishes. The entire Universe, high and low, belongs to Him. All of them are His servants and slaves, and are utterly dependent on Him.
Al-Waahid (the One), al-Ahad (the Unique). He is the One Who is uniquely and utterly and perfectly One, with no partners in His Uniqueness. His slaves are obliged to believe in His Oneness, in belief and word and deed, by recognizing that He is absolutely perfect and is unique in His oneness, and by directing all kinds of worship to Him Alone.
Al-Samad (The Self-Sufficient Master, Whom all creatures need, He neither eats nor drinks). He is the One to Whom all of creation turns for all of their needs, for He is in and of Himself absolutely perfect, in His Names and Attributes and Deeds.
Al-‘Aleem (the All-Knowing), al-Khabeer (the Aware). He is the One Whose Knowledge encompasses all things, seen and unseen, secret and open, everything that is inevitable or impossible or possible, in heaven and on earth, the past, the present and the future. Nothing whatsoever is hidden from Him.
Al-Hakeem (the Wise). He is the One Who has ultimate wisdom, in His creation and in His commands. He is the One Who created everything well.
“… And who is better in judgement than Allaah for a people who have firm Faith.” [al-Maa’idah 5:50 – interpretation of the meaning].
He does not create anything in vain, or legislate anything in jest. He is the One Who has Dominion in this world and the next. His ruling applies in three major spheres, in which none else has any share with Him: He judges between His slaves by means of His Law, His decree and His reward/punishment.
Wisdom: He puts things in their rightful places and gives them their rightful status.
Al-Rahman (the Most Gracious), al-Raheem (the Most Merciful), al-Barr (the Source of Goodness), al-Kareem (the Most Generous), al-Jawaad (the Generous), al-Ra’oof (the Compassionate), al-Wahhaab (the Bestower). These names are all close in meaning, and they all indicate that the Rabb is characterized by mercy, goodness, and generosity. They testify to the vastness of His mercy and other attributes, with which He encompasses all of His creation to the extent that His wisdom decrees, although the greater share is bestowed upon the believers in particular. Allaah says (interpretation of the meaning):
“… My Mercy encompasses all things. That (Mercy) I shall ordain for those who are the Muttaqoon (pious)…”
Blessings and goodness are all traces of His Mercy and Generosity. The good things of this world and the next are all traces of His Mercy.
Al-Samee’ (the All-Hearing). He hears all voices, in all the different languages, no matter how many and how varied, when they call on Him for their needs.
Al-Baseer (the All-Seeing) Who has insight into all things, not matter how small. He can see a black ant walking across the face of a rock on the darkest night. He can see what is below the seven levels of the earth and what is above the seven heavens. He is the All-Hearing and All-Seeing, Who knows who is deserving of reward or punishment according to His Wisdom.
Al-Hameed (the Praiseworthy), Who is inherently deserving of praise, by His Names, Attributes and deeds. He has the Most Beautiful Names, the most perfect attributes and the most perfect and beautiful deeds. His actions always revolve around munificence and justice.
Al-Majeed (the Most Glorious), al-Kabeer (the Most Great), al-‘Azeem (the Most Great), al-Jaleel (the Sublime One). These Names describe Allaah with attributes of glory, pride, greatness and majesty. He is greater than everything, more mighty, more majestic and more exalted. To Him belong glorification and exaltation in the hearts of His close friends and devoted slaves, whose hearts are filled with veneration of His might and humble submission to His glory.
Al-‘Afuw (the Pardoner), al-‘Ghafoor (the Forgiver), al-Ghaffaar (the All-Forgiving), Who has always been and will always be known for His pardon and forgiveness towards His slaves. Everyone is in need of His pardon and forgiveness, as they are in need of His mercy and generosity. He has promised to forgive and pardon whoever follows the appropriate means. Allaah says (interpretation of the meaning):
“And verily, I am indeed Forgiving to him who repents, believes (in My Oneness, and associates none in worship with Me) and does righteous good deeds, and then remains constant in doing them (till his death).”
Al-Tawwaab (the Acceptor of Repentance). He always accepts the repentance of those who repent and forgives the sins of those who commit sin. Allaah accepts the repentance of everyone who repents to Him sincerely. He is the One Who forgives those who repent, firstly by helping them to repent and causing their hearts to turn towards Him. After they repent, He turns to them and accepts their repentance, pardoning their sins.
Al-Quddoos (the Holy) and al-Salaam (the One Free from all defects). Allaah is far above any attribute of imperfection, and He is above being likened to any of His creation.
“… There is nothing like unto Him…”
“And there is none co-equal or comparable unto Him.”
“… Do you know of any who is similar to Him?…”
“… Then do not set up rivals unto Allaah (in worship)…”
The names al-Quddoos and al-Salaam reject the idea that He could be lacking in any way, and they imply that He is absolutely perfect in all aspects, because once the idea of imperfection is rejected, this is proof of total perfection.
Al-‘Aliyy (the Exalted), al-A’laa (the Most High). He is the One Who is completely exalted in all aspects, in His essence, in His status, in His attributes and in His dominion. He is the One Who rose over the Throne and Who dominates all things. In all the attributes of might, pride, glory and beauty that are ascribed to Him, He reaches the ultimate level.
Al-‘Azeez (the Almighty), to whom belong all might and power, the power of strength, the power of dominion, the power of invincibility. None of His creatures can harm Him. He has subjugated all that exists, and the whole of creation is under His control and is subject to His might.

He sent His Messengers and revealed His Books with signs and proofs, and confirmed His Messengers with signs and proofs, to confirm the truth of the message they brought.

Al-Qadeer (the Powerful), Whose power is perfect. By His power He created all things that exist, by His power He is controlling all things and by His power He formed them and perfected them. By His power He gives life and death, and will resurrect His slaves to receive their reward or punishment, so that those who have done well will be rewarded with good, and those who have done evil will be punished. When Allaah wills a thing, He merely says “Be!” and it is. By His power He controls people’s hearts, and He directs them as He wills.
Al-Lateef (the Most Subtle and Courteous), Whose knowledge encompasses everything that is hidden and concealed. He knows everything that is secret and understands the most subtle things.

“Allaah is the Walee (Protector or Guardian) of those who believe. He brings them out from darkness into light…” [al-Baqarah 2:257 – interpretation of the meaning].

General provision, which include the righteous and immoral, the first and the last. This is the provision of physical needs.
Specific provision, which is provision for the heart which is nourished with knowledge and faith, and the halaal provision which helps a person to adhere to religion. This provision is specifically for the believers, and is given to varying degrees according to His wisdom and mercy.

He is the One Who initiated His creation in stages, and Who is constantly renewing it.
Al-Fa’’aal lima yureed (the One Who does whatever He wants). This has to do with the perfection of His power and the strength of His will and ability. Everything He wants, He does, with nothing to stop Him and no one to oppose Him, and with no support or help, no matter what it is. If He wants something, all he has to do is say “Be!” and it is. Although He can do whatever He wants, His will operates in conjunction with His Wisdom, may He be praised, so He is described as being completely Able and being Strong of will, but also as being completely Wise in all that He has done and will do.
Al-Ghaniy (the Self-Sufficient), al-Mughni (the Enricher). He is independent in and of Himself, and is completely Independent in all aspects, because of His perfection and the perfection of His attributes.

He cannot be anything but Self-Sufficient, because this self-sufficiency is one of His essential qualities, just as He cannot be anything but the Creator, the Able, the Provider, the Kind, Who does not need anyone else at all.
He is the Self-Sufficient in Whose hands are the treasures of the heavens and the earth, the treasures of this world and of the Hereafter.

Whoever draws near to Him with something of righteous deeds, He draws near to him by more than that.
Al-Qareeb (the Ever-Near), al-Mujeeb (the Responsive). Allaah, may He be glorified, is near to everyone, and His nearness is of two types:
His nearness to everyone in a general sense, through His knowledge, watching, awareness and witnessing, which encompass all things.
His nearness in a specific sense, to His slaves, those who ask help of Him and those who love Him. The true nature of this closeness cannot be understood, but its effects may be seen in His kindness towards His slave, and His care, support and help of him. Another of its effects is His response to those who call on Him and His acceptance of the repentance of those who worship Him. He is also the One Who responds in a specific way to those who respond to Him and follow His religion.

The Prophet (peace and blessings of Allaah be upon him) explained this in a clear and comprehensive fashion when he said, addressing his Lord: “You are the First, and there is nothing before You; You are the Last, and there is nothing after You. You are the Manifest and there is nothing above You; You are the Hidden and there is nothing beneath You.”
Al-Waasi’ (the All-Encompassing). His attributes and qualities, and everything that has to do with Him, are all-encompassing in such a way that no one can praise Him as He deserves, but He is as He praised Himself, vast in power, might and dominion, and vast in grace and kindness, and vast in generosity and munificence.
Al-Haadi (the Guide), al-Rasheed (the Guide to the Right Path). He is the One Who guides His slaves and shows them the way to all that will benefit them, and protects them from all that will harm them. He teaches them what they do not know, and guides them to the true guidance which will help them and set them straight. He fills them with taqwa (piety) and causes their hearts to turn to Him, in response to His command.
The name al-Rasheed has a meaning akin to that of al-Hakeem: He is Wise in word and deed, and all His laws are good and wise. His creation testifies to His wisdom.
Al-Haqq (the Truth). He is true in and of Himself and in His attributes. His existence is undeniable, and His attributes are perfect. His existence is one of His essential qualities (He cannot but exist), and nothing else can exist except through Him. He is the One Who has always been and will always be described with attributes of majesty, beauty and perfection. He has always been and will always be known for His Kindness. His words are truth; the meeting with Him is truth; His Messengers are truth; His Books are truth; His religion is the Truth; the worship of Him Alone, with no partners or associates, is the Truth; everything that has to do with Him is truth. Allaah is the Truth and whatever else they claim to be divine besides Him is false. Allaah is the Most High, the Most Great, as He says (interpretation of the meanings):
“And say: ‘The Truth is from your Lord.’ Then whosoever wills, let him believe, and whosoever wills, let him disbelieve…”
“… So, after the truth, what else can there be, save error?…”
“And say: ‘Truth has come and falsehood has vanished. Surely, falsehood is ever bound to vanish.’”[al-Isra’ 17:81]
