I think the adults have a specific pair of teams between them. One of my headcanons is that Ozpin was the Proto-Ruby while Port was the Proto-Jaune. Port's loyalty to Ozpin may stem from the idea that their team had worked together for a long time.

While it can easily be assumed that Port is a member of Ozpin's team, he doesn't thematically match the Wizard of Oz motif that Ozpin has.

I think Port, and Oobleck were teammates and probably a generation (I'll refer to their generation as 2nd generation) ahead of the Wizard of Oz team, composed of Ozpin, Ironwood, the Lion and Qrow. (The 1st generation)

Glynda, I'm still unsure. Peach is another crazy factor. Summer is likely from the 2nd generation as well.

Cinder is definitely younger than those above, making her likely a part of the 3rd generation. I'm also very sure we haven't seen her teammates yet. Or worse, we won't see them anymore.

Emerald, Mercury and Neo are part of the 4th generation and probably only a few years (like 1-2 years few) older than the main cast, the 5th generation. Connections with Cinder's associates and Neo are still unclear since we have no information to work with.

Due to Roman and Junior's current... occupation, I presume that they're drop-outs. That can sort of explain Roman's dislike for schools. Eh, that's a speculation for another day though.

That's mostly my theory at the moment.
