Maul's pretty much the only one that can at least hold him off in any given duel. Ventress's form is ill-suited to deal with a fighter as skilled, powerful, and prone to dueling as Caedus. He'd power through in a similar fashion to an enraged Anakin, or dispatch her via the force as he did to Saba Sebatyne in their confrontation on the Anakin Solo.
Savage can probably pose a minor distraction if enraged, but Caedus vastly surpasses him in skill and can take him out via the force as well. If there was a more offensive duelist for team 1, they might have a chance at a few wins. But Ventress would get stomped due to Makashi's weakness to offensive fighters, and Savage simply can't compete with Caedus.
Maul lasts a bit and then dies.
