Regarding this topic: Satan is a fallen angel.
You are correct.
We covered this topic in my Bible Study. Lucifer was the angel who wanted to be “above God” in every way. After he was cast out of heaven with his follower fallen angels, he was named Satan.
For anyone on this thread who is interested in reading the actual Scripture:
Ezekiel 28
Isaiah 14
Good explanation on Christianity.com “How did Lucifer fall and become Satan” is the title of the article.
