intermission

If you stay in intermission after a match do you play the people you previously played?

If they don’t leave then ya

I don’t think I ave every stayed with a group unless I was in a fireteam.

No

I am pretty sure you don’t. At least it my experience it rematches you each time. So there’s a chance you could see the same people, especially since they’d likely be starting a search at the same time (even more likely in games like BTB or Warzone with lots of people) but there is no guarantee.
