After Nikaah (if final ceremony is not done), are you allowed to meet each
other, similarly travel together and are you allowed to shake hand and hug
each other?
The answer is, yes, all of this is permitted, even if it happens before the wedding
party, so long as the contract has been drawn up according to Sharee’ah, with a
guardian and two witnesses, and the proposal has been given and accepted, and both
parties consent to the marriage. And Allaah knows best.
