No they are not one is a arch angel while Lucifer is fallen angel.

Lucifer has not yet died on Supernatural. However, in Season 5, episode 19, he kills his brother Gabriel. Lucifer is currently trapped in a cage in Hell with his older brother, the Archangel Michael. They both fell into the cage when Sam Winchester (possessed by Lucifer at the time) was able to regain temporary control over his body and open the portal, pulling Michael (who possessed Sam and Dean's half-brother Adam) down with him, ending the Apocalypse. Now that Lucifer and Michael are safely caged up, Crowley (king of the crossroads demons) has risen to the rank of King of Hell and is more powerful and dangerous than ever.
