1) She takes the trio with her immense Force powers. Personally, I'd rank her below Obi-Wan and Anakin in saber ability, but she is superior to all three in Force powers, by far. Traya wins.
2) Though General Grievous is stronger and faster, he - again - can't use the Force and expect to survive someone as powerful as Traya. Traya wins.
3) A Grievous moment. Maul is quicker, stronger, and the better duelist, but would be annihilated through the Force. Traya wins.
4) Mace Windu is like Maul and Grievous before him. He is superior to her, by far, in saber ability, but we've seen nothing that can allow him to defend himself from Traya's Force powers. Traya wins, though this fight would be harder than the others.
5) Count Dooku is with Mace Windu. He also has the advantage of some pretty potent Force powers himself, but is outclassed and dies when Traya uses the Force. He would be a hard opponent.
6) Traya here takes on the two most powerful Force users of their era. She eclipses both of them in ability in the Force, but she is inferior in saber ability - and I doubt she can survive the onslaught that both of them present. Even if she kills one, the other would quickly take her out. Traya loses.
