Angelfish are very sedate fish so you'd be good to go with other sedate, gentle fish.
Non-agressive catfish (idk about cories because they're hyper) You'll want calm ones.
Theres some tetras that are decent but no names are coming to mind, you'll have to look. i think diamond tetras are okay? Don't quote me on that though
No gourami's or bettas, many of the tetra species, danios, and no discus
Sorry I'm not all that specific but hopefully this gives you an idea of where to start looking.
