How many types of angels are in the bible and the books it in?

Answer 1

There are very many different types of angels in The Bible; used by God for many different purposes, but I suppose thee are two main types:

God's good angels, and the bad angels who follow Satan. But there are more good than bad, as the prophet said to his servant who saw angels

And he answered, Fear not: for they that be with us are more than they that be with them.

And Elisha prayed, and said, LORD, I pray thee, open his eyes, that he may see. And the LORD opened the eyes of the young man; and he saw: and, behold, the mountain was full of horses and chariots of fire round about Elisha (2Kings 6.16,17)
