The Archangel's ages--Michael, Lucifer, Raphael and Gabriel. It hasn't been explicitly stated when Metatron was specifically born, but I recollect a comment in a Supernatural companion guide made by Eripke himself--Gabriel's THE youngest, but this articulated when Eric was running things. So it could easily be argued Metatron is younger than Raphael and older than Gabriel, otherwise his age placement would be contradictory.
