It is not permissible to ask fortunetellers questions, because the Prophet (blessings and peace of Allah be upon him) said: Whoever goes to a fortuneteller and asks him about anything, no prayer will be accepted from him for forty days.” Narrated by Muslim (2230). This applies to the one who asked him a question without believing him. However, if he also believes that, then the matter is more serious, as the Prophet (blessings and peace of Allah be upon him) said: “Whoever has intercourse with a menstruating woman, or with a woman in her back passage, or goes to a fortuneteller and believes what he says, has disbelieved in what Allah sent down to Muhammad (blessings and peace of Allah be upon him).” Reading the words of fortune tellers and soothsayers is haraam (forbidden); it is like asking them questions. If you deliberately read their words, then repent to Allah and seek His forgiveness, and do not do such a thing ever again.

Kissing the Black Stone is an act of worship in which a Muslim kisses a stone to which he has no connection except worshipping Allah by venerating it and following the Messenger of Allah (peace and blessings be upon him) by doing that.
