Damsels are territorial, so having 8 damsels in a system will be very stressfull on them except in a large system.

As others have pointed out, quarantining the new fish would have probably prevented the quick deaths of all the fish.
What types of damsels did you have before, and what kind were the new ones? Are they known to live together peacefully? Most damsels don't live together very well. In a pet store, they may keep a lot together when selling them like clownfish, but when you get them in smaller groups, they tend to kill each other off.
