Ditch the damsels. Seriously dig them all out. Sell them back to LFS for credit.
Favorite easy fish:
Vroliks or Melanarus wrasse ($30-40), Coral Beauty Angel ($15-30), Orchid Dottyback ($25-40), Bangai or Pajama Cardinals ($10), Pairs of fairy wrasses (both male OK, $20-400 lol), Yellow Watchman Goby ($20), Green Chromis ($4-7), Firefish ($10-30), Yellow Tang ($20-40), Yellow Foxface ($20-40), Flame Hawkfish ($30-50), Ocellaris Clowns ($10-30), Black Ocellaris Clowns ($20-50).
I think that gives you every color, several shapes of fish, and they're all pretty hardy in my opinion. I would avoid nearly any other angel, and most other tangs until more established. Even sailfin tangs can be edgy in new tanks. Purple tangs are hardy as snot too (perhaps hardier than yellow) but they fetch $150-300 so I didn't mention them. Buy the above fish and you'll have a neat community.
I keep several fairy wrasses of multiple colors and they're awesome additions. I also recommend the vroliks wrasse (search live aquaria) over the melanarus. They're prettier, more vibrant greens and blues, just as hardy, and less skittish (not that melanarus are skittish by any means though).
