The original second picture is NOT a convict! Maybe a hybrid, but no pure convict. The first one is NOT african, is it amphilophus labiatus, AKA a red devil. Note the think lips (which is where the latin name labiatus is derived from). The last two are in fact convicts, however, I am not sure on the sex as they can be quite hard to accurately sex.
