AnswerPeople seem to have come up with so many names and legends about the devil, so it is hard to give any answer that has the least provenance. Even the name 'Lucifer' for the devil is a misnomer.
It arises because of a passage in Isaiah chapter 14, which talks of the pomp and splendour of the king of Babylon, who had ruled the nations in anger, and his fate after his overthrow by the king of Persia. He had compared himself to the morning star (Lucifer, from Latin - think of English words such as 'lucid') and had thought that he would ascend into heaven and sit among the stars, but was now himself persecuted. He has become weak and like one of us; he will go to hell. This passage was misunderstood by early Christians as discussing the devil, and so Lucifer became another Christian name for Satan. And rather than the king "falling" from heaven, we have the devil falling from heaven.
