Having more FB profile under same name & surname, problem ?

Is it problem to have few ( 2-5) FB profiles under same Name & Surname ? Will that cause problem from Facebook ban ? If, yes, If I change name & surname of that FB profiles, will it better or to be 100% sure better to delete that kind of profiles under same name& surname ?

At least, how many FB profiles under same name and surname can be on Fbook ?

In my experience(not much), names dont matter much. What really matters is how you register the site.

What do you mean by that "How you register site" - which site ? Could you explain a little , thanks ?
