1-3. When Gabriel joined his pagan family he told them he was a god named Loki. Loki does not exist, as he is just a describe for Gabriel.

4. No, only crossroads demons or higher can teleport. Even then, these beings need a vessel to travel between earth and He'll by teleportation.

5. This depends on how you look at Seraphim. Lilith was stronger than some of the Angels we have seen on the show, such as Castiel before he became more powerful in Swan Song.

6. I have no clue, to be honest. Nothing has been set, and so the most powerful probably hasn't even been introduced.

7. These deities most likely exist within the universe.
