what odds do I need to call raises with Ax suited

[joop]

Quick question that has been at the back of my mind for a while now. Usually I just wing it, but maybe somebody could give me a definite answer.

Say I'm on the button in a full ring limit game and UTG raises, how many people need to call his raise before I can also call with, say Ax suited, or suited connectors, say 56s? Assume the blinds are very passive and rarely 3bet preflop.

Also, what about in the small blind, assuming I have the same two types of hands, how many callers do I need before I can jump in too?

And in the BB, how many callers before I can call with some randomly suited hand like 93?

Would be much appreciative of an answer on this, as I'm sure my "3 people have called, I'm in" method isn't very accurate.

Cheers.
