I think the lethinthrops should be ok a 5 inch fish but the other two are too big you want them that are 5-6 inches in this tank and no bigger.
It is a bit like a game of chess you need to find a mix of fish that are not too related eg one of each family (apart from peacocks) and that look different enough (including peacocks) so they don’t fight too much.
But you do need to be aware that there is nothing guaranteed in terms of aggression or if all of your fish will colour up 100% some might be too submissive to go full colour. It’s one of the reasons a group of 5 labs with 4-6 peacocks or haps might not be a bad choice as the labs would always be coloured up.
