The Forgotten Realms has most of these

Vampire Dragons: https://forgottenrealms.fandom.com/wiki/Vampiric_dragon

Demon Unicorns: https://forgottenrealms.fandom.com/wiki/Black_unicorn

Skeleton Wizards: https://forgottenrealms.fandom.com/wiki/Lich

Fey Werewolves: https://forgottenrealms.fandom.com/wiki/Brokenstone_Vale

The only think I don't have on hand are angel ghosts and lochness mothmen in the Forgotten Realms, though I think you probably could find the former.
