Hum my take i guess would be like this. Only for some though.

Alyssa she teaches at a local kindergarten still.
Tori is still a ninja teach and surfs when she doesn't have to teach.
Conner is a famous soccer star.
Ethan is like the microsoft of that planet. He's a genuis and all.
Kira finally got her singing career off the way she wanted to and is running it the way she wants to.
Trent draws comics for the local newspaper.

Hum haven't given a lot of thought in the others though.
