Suitable mix of fishes

Bro,

Currently i have 3 types of fishes, Oscars, Parrot fish and Koi...
They are more or less the same sizes now..

Currently, Oscars and Parrot are in first tank and Koi in second tank.
The thing is i am going to move them to a third bigger tank and wonder what is the best mix...

Option A: Oscars and Parrot
Option B: Oscars and Koi
Option C: Oscars and Parrot and Koi

Any bro has similar mix ?

Tank is 6 feet, 2.5 feet high and 2.5 feet wide.... sump is 5 feet.

Already 'pour' all the parrot and Koi into the tank....
Left the Oscars alone for now... They look fierce...
