Sabers only
Plagueis is superior to everyone sans Revan - although mainly by inhuman physical advantages; Caedus is similarly superior to everyone sans Revan. Galen, on the other hand, is slightly beneath Krayt, equal to Vader, and inferior to Revan.
It honestly depends on the matchups. Nobody from Team 1 can defeat Revan, but everybody can stall Revan for a while... There is a huge chance that if Caedus fights Revan, by that time Plagueis or Caedus are done with Vader or Krayt, and Revan won't win against two at the same time.
Team 1 for a majority here.
Force only
Plagueis overwhelms Vader in short order, and while Krayt would put up a better fight, he is outmatched too; Revan would obviously defeat Plagueis, but gap between Revan and Plagueis isn't larger than between Plagueis and Vader.
Caedus overwhelms either Vader or Krayt in a great fight, or gets destroyed by Revan.
Galen probably falls to Krayt, defeats Vader barely and gets murdered by Revan.
Complete toss-up.
All out
Team 1 barely probably.
I feel like plagueis and revan are the two strongest
If they go at it it'll last for ages and dunno who would come out on top
So then caedus takes on krayt and wins and helps galen with vader
Then all three gang up on revan and destroy him
Team 1 wins
However different matchups could cause different results
