RNJR doesn't own vehicles. Nora and Ren are orphans, and they could use public transportation in Vale, so why would they need their own vehicles? Jaune likely took public transportation to Vale from his family's home and thought he was gonna be living at Beacon for the next four years. Ruby may not be old enough to drive.

I'd guess that Ilia wasn't checking her Scroll in the middle of battle, but rather trying to call for help using the local service to contact any nearby WF members. Blake and Sun were trying to catch her, and she couldn't let that happen. She found herself cornered, so she tried to call for help, but Blake kicked it out of her hand.

Probably just the Vale sect of the WF that believes in and follows Adam, maybe with some others in Mistral starting to follow him. He certainly has Menagerie branch members following him, as well.
