What's the status of phase 1-3 characters?

When you say TV folk you mean like Falcon and Winter Solider or the new ones like She Hulk and Moon Knight?

I'd imagine Thor would show up in Guardians of the Galaxy 3 and Thor 4. Hulk will surely pop up in something as well.

As for Avengers line up, I'm not sure, I don't think were meant to be sure. On the wiki it says

"After a year, there was no activity from the Avengers, causing the world to grow concern about their whereabouts or if they were even still around at all. Seeking answers from the person who would know, people began to ask Nick Fury, unbeknownst that it was actually Talos impersonating him while he was on vacation in space."

It'll be years before Avengers 5 so by then they may have figured out who is still going to be around for them to form a team around. Otherwise I'd say it's probably disbanded at the moment.
