Keeping Damsels in groups?

[Tnops]

Hey fellas, what do y'all think about keeping 3 chrysiptera (looking at talbot's and rolland's) damsels in a 75 gallon with the following tankmates?: https://www.reef2reef.com/threads/semi-aggressive-reef-75g-stocking.929580/

If it can be done, will they group or will they just do their own things? Also can you keep different types of chrysiptera damsels in the same tank?

I have four (4) damselfish in my 160-gallon display: three blue sapphire and one azure. They all get along very well - but I also have lots of rockwork to provide ample hiding/sleeping space.
