Angelfish in 120G

[fishie111]

Hi-

I currently have a 120G (5' x 18in x 24in) with 2 angels, 2 festivum, 6 geos. pindare (max size 4-5in), 4 keyholes, cories, hatchets and pristella.

Can I add more angels? If so, how many?

If I remove the keyholes, would the answer be any different?

What about if I removed the keyholes and festivum?

Thanks!
