When you have a tank that "isn't supposed to work" but it is...any change can wreck the delicate balance.
When you have so many species, limiting to all-male usually works better because it eliminates fighting over females.
So if you want to try to salvage as many of the current inhabitants as possible, remove females and look-alikes and shoot for 8 mbuna in the tank.
If you want to try groups, I would avoid jewels since they are likely to try to kill everyone when they spawn. Choose 3 species and stock 1m:4f of each. Each species should be a different genus and red zebras have a rep for cross-breeding with yellow labs. You have a lot of Metriaclima in your tank (red zebra, albino zebra, kenyi).
I'd go for some more peaceful species like yellow labs and Cynotilapia sp. hara.
