You could put quite a few in there, but I would focus on the mix of LJ/UJ personalities and how often you want to do water changes/tank layout for the fish.
Of course the big 3: ornate, teug, weeksii, will be fine with LJs. Dels can also be fine because they can get big and girthy. Like

said, I'd be more worried about the senegals depending on how large they are and how they get along with the other fish. It has been done before, but there is a risk the sens might get eaten depending on the size difference and the hunger of the LJs. Can't speak to the ropefish.
