No tang should be kept in 50 gallons. The yellow tang will grow to about 6 or 7 inches at minimum across and neds huge amounts of open water for its swimming needs. Even the smaller tangs such as Bristletoothes will need 60-70 Imperial gallons.
Small reef tanks raelly should only deal with dwarf angels rather than tangs due to the very nature of tangs and their needs. These fish as also highly strung ans very easily stressed, cramping them will only increase the territorial needs and put more pressure ontheir stress levels which means even more chance of catching whitespot or evenworse Oodinium.

The rest seem fine however i would urge caution with the butterfly as they are known muncher on coral polyps.
