The Names of Angels in Fantasy

Sabrina Willis says, hello and Merry Christmas. I have a question in regards to the names of angels that I found listed on a Wikipedia page, Angels in theology. Many of these angels are watchers from the book of Enoch. And are fallen angels. Is there any real danger in using these names as character names in a fantasy story I'm writing? Do not be scrupulous about this. Names do not have any intrinsic power. They're just sounds.
