Answer 1

Not very advisable.  Firstly, you haven't listed your tank size for one, and two, the water parameters.  What you are asking to do, is pair a hybrid south american (Flowerhorn) with a Tangyangikan (Frontosia) and another South American (Green Terror) rule the tank type.

Small or large, to me, doesn't matter.  You are trying to mix very highly aggressive South Americans with an African, though grows large, doesn't carry the same temper the GT and FH do.  That's not even addressing the completely opposite water needs.  You're best bet, just keeping 4 FH's alone, that's about a 150 gallon plus tank, and that is being VERY generous.  The GT should be by itself, probably in a 55, and the Fronts their own 125.

Now let's just say for the sake of answering, you could meet an inbetween need on the water chemistry.  You're talking about large fish here, and I would not even think to try this in anything under a 250-300 gallon tank, and again, that is being very kind.  The tempers, water needs, and sizes make this very much, not a good idea to think about.
