Luke Skywalker
Anakin Skywalker (zone)
Jaina Solo
Jacen Solo
Leia Solo
Kol Skywalker
Cade Skywalker
vs.
Darth Sidious (RotS)
Darth Plagueis
Darth Tenebrous
Darth Bane
Darth Zannah
Darth Tyranus
Darth Maul
Luke beats Palpatine in the longest fight possible.
Bloodlusted enraged Anakin beats Tenebrous.
Jaina beats Bane in a good fight.
Jacen and Plagueis is the most debatable I guess, but it shall definitely take long.
Leia, Kol and Cade lose to Zannah, Tyranus and Maul, but they give a good fight.
Probably Skywalker team is in a better position.
