6 angles
4 gouramis
4 rosy barbs
3 bristlenose
1 rainbowshark
Be first sure that those 3 plecos are same sex - otherwise you'll have hundrets of new plecos! Bristlenoses breed like rabbits.
Yes, you can add these fishes:
6 corys
6 kuhli loaches
as well as another 4 rosy barbs
But don't add more, because when those angles are adults, they are huge and need room. Probably they can be in the same tank if they don't start to fight. When they are young they usually shoal together, but when they are adults they usually mate. And especially then when they breed they need some space too and don't tolerate other angels near.
what are water values? But it sounds pretty good to me. Maybe after you have added more fishes, you may need to do more water changes or larger - 25-30% every 4. day. When those angels are adults, you need to change more water.
