how many?

Depends on what kind. most kinds, in a 10g, none.

You could however have something like a) a pair of lamprologus brevis, or b) a trio of lamprologus similis or lamprologus multifasciatus, or c) a pair of apistogramma species.

What kind of cichlids are you interested in?
 
Sounds as if you need to forego the idea for now until you can get a bigger tank. Maybe a 20 long and then get some rams or apistos.
