Males vs females

[bunzplayer]

I have 5 African cichlids.

2 Electric yellow
1 cobolt blue
2 marbled mnuba

Is it possible to only have 1 female in this tank? The others I thingk are males. One of my Electric Yellows has already had 2 sets of fry now so I know she is female.
Is it possible that the remaining 4 are all males fighting over this one female, or is it possible that another is female, but not sure?
