The type of cichlids I have are electric yellow and blue, acei, jewel, peacock, and various other colors such as powder blue, black/yellow, albino, beige/black stripes. Everyone seems peaceful at the moment.
With those species you listed (even without the unknown ones) your tank is not going to be large enough once they reach sexual maturity. The acei, black/yellow , beige/black (likely a Ps. crabro and/or M. auratus) are not suitable for a 50 gallon tank (they get too big and/or are to aggressive for the space alotted). It is very important that you get your fish all identified.
Having cichlids is very different from having a tropcal community tank. There are very specific guidlines for compatability due to the great amounts of aggression and territorial issues that happen with cichlids. Everybody is fine while they are all juveniles, but when they reach sxual maturity (way before they reach physical maturity) they will begin to fight and possibly (more like "will definitely") kill off any they don't want around.
This is the hardest thing for new cichlid keepers to accept. Any one of you fish could easily claim an entire 50g tank for himself and cause world war 3 trying to get everyone else out of his territory.
