In order: 1. Volume 9. 2. Asuna eventually gains access to a Super Moderator Account that gives her a new avatar (which is based on the Underworld's goddess) and leads the charge to rescue Kirito (who is catatonic at this time) as well as protect the denizens of the Underworld. 3. It's hinted in the end of the Ordinal Scale movie, but nothing has been "officially" announced as of yet. 4. the LN series is ongoing and currently at Volume 19. Reki Kawahara said that he's going write one final and large story arc before SAO ends.
