When you have a lot of fish in your tank and then remove some, it changes the whole dynamic of the tank. It was definitley a good move for you to remove the mbuna for their sake, but now you can see that they were dithers for the other members of the tank. Everyone will be looking to define a larger area as their own, with less fish, there is more land to claim! So it may take a few weeks before everyone settles in.
Keep your eye on the aggression, you have to let them sort it out, but as long as no one is missing scales or tails, and no one is up in the corners of the tank, then I wouldn't worry too much. However, you still have issues with the size of your tank and the fish you have chose to keep. Peace is not going to last long, once they are sexually mature more aggression will occur. If your JD's were to breed, there probably won't be any tankmates that will survive that.
