I've just done some quick research and there is a site online called African cichlid that you could look on and identify these fish
I've also had a better look at the early pictures and there looks to be a Juwel cichlid there (5th picture down, next to a yellow mbuna cichlid) there also looks to be an apistogramma there aswell ... both of these fish are SA cichlids so there's two different types both needing the complete opposite water requirements - old world cichlids (African) need alkaline water and New World cichlids (South American) need acidic water.
Juwel cichlids are also on the aggressive side and you need to be careful what you keep with them. The apistogramma tends to be a shy fish and so how that's coping living with the more aggressive types I don't know.
Do you have an option to re-home some of these fish?
