Again, you'll ned to define what "some angels and a few others" means. If you are talking about large angels, like queens, french, etc, then absolutely. The larger, the better, and there is still no guarantee that they will tolerate one another. They are very territorial. Everything depends on what fish you want. In this case, you need to build the tank to the fish you want, so you may want to get a few books and decide which species you want to keep.
