From what I've learned, Lucifer is a fallen angel. Fallen angels are, in Christianity, the ones that rebel against God. God casts them out of Heaven, or they either chose to leave themselves.
Since Lucifer rebelled against God in the bible, The Lord cast him out of Heaven and Lucifer wanted his own power thus making him a fallen angel.

The biblical Lucifer is also called light bringer. It's said he was the most beautiful, most favored, most powerful, etc... angel which led to his vain belief he was better than God. As a result of this vanity he led a revolt that ended in his cast out of heaven along with those who sided with him/fought along side him.
