Sorry you had to pm me, I'm usually FULL of advice. Life has just been busy.
Ok, I will happily give you my suggestions, but at the end of the day these are your tanks. Before I joined this forum, I was told that I would never find Mbunas mild enough to be with any Peacock... And my tank has settled down nicely after fixing one issue.
I would put all your Hap & Peacocks in one tank and work towards an all male tank. I do not know if all the ones you have are compatible but you can research that. If it turns out that you have a breeding pair or trio in your juvies, you can TRY putting them in with the next two tanks listed, it might work. That also might be a good option for a male that looks too similar to one of your other males.
Tropheus are way more prone to bloat than anything else on the list so be careful who you house them with. The Acei's tend to be food hogs so my best GUESS would be to keep them alone or try them with the Greshakei (mine are pretty mellow) and maybe the albino socolofi. You might want to add 3 or 4 more Tropheus and soon cause they do better in groups of 10+, from what I've read.
The blue Dolphins, yellow labs, Acei, powder blue Socolofi, and the 1 Demasoni may all work together. You should be trying for 1M/3F ratio, or 5 females in a bigger species group, on everything in the tank EXCEPT the Demasoni. You might be way better off with just 1 of those.
You might could try the White Top Hara with some red zebras, both are spunky but the red zebras might be more so. You probably have more red zebras than you have space for, IMHO.
I had bad luck with Kenyi my first try because they were so aggressive and I can not give you any good advice on them. I ended up having to rehome mine by 2" in length. I would personally list them as the most aggressive Mbuna on your list.
This is probably not exactly what you were hoping for but it is the best I can do. Most of my experience is with Mbunas. Matching aggression levels can not be overlooked when stocking. Hope this helps.
