Blue Hippo, Lieutenant, Powder Brown, Naso all need tanks a minimum of 6 feet long term (ideally 8 foot long tank for some such as the Blue Hippo and Naso)
2-3 Yellow Tangs in a 5 foot tank would be a recipe for aggression unless they happen to be a mated pair. Yellow Tangs, Lieutenant, Naso are all among the more aggressive Tangs to boot. A single Yellow Tang would be best for that tank maybe with one other smaller bristletooth tang (ie Kole, Two Spot, Squaretail). Just be aware that the Yellow Tang will likely try to bully the smaller more peaceful fish.
If I were doing it I would swap the Yellow Tang for a One Spot Foxface, much better around other fish and they will give you that similar slender profile fish that gets good sized. Then add a small Bristletooth Tang. I would also skip the Chromis as they will generally pick each other off over time. The Firefish might also be bullied by more aggressive fish. My Purple Firefish was the number 1 target of any larger/more assertive fish that I had and it's almost identical to the Exquisite.
I would modify the list to look something like this as your list would be grossly overstocked for your tank (keep in mind that Tangs are super dirty and poop like you wouldn't believe):
Pair of Occ Clowns
McCosker's or Carpenter's Flasher Wrasse
Anthias of Choice
Royal Gramma Basslet
Neon Goby
One Spot Foxface
