The only African cichlids you can fit in a 10 gallon tank are shell dwellers from lake Tanganyika. Typically, unless you are fully aware of the behavior of the specific species, Africans should never be mixed with community fish, and should never be kept in a tank so small. As you have found out the hard way, these fish are very aggressive and territorial, and you can never provide too much space for them.
All I can suggest is returning all of your cichlids and starting over with the proper research.
Good luck.
