No she doesn't.
Captaian Rex apears ONLY in Star Wars The Clone Wars in bothe the movie and show.
Nobody know Ashoka's fate yet.
Yes He Got Shot By A Commando Droid Along With NUB.
No.the reason he didnt was because he was one of the best of the corasaunt guard commanders.the chance that he died is very low because he never really participated in a all out war like cody,rex,or gree.the only reason people say that is because they think thire took his place.the truth is that thire is a escort clone not a senate guard,which means fox did not die.that would suck if he died.
This is a possibility. At starwars.com, the trailer for season 3 is all about Ahsoka. She is talking to master Yoda, and saying that she is having dreams (kind of like Anakin dreaming about Padm'e dying in Revenge of the Sith), although she does not say what it is about, the trailer also shows Ahsoka in some sort of dark forest, Shaak Ti walking with a Kaminoan on Kamino, Anakin with Aksoka, Ziro the Hutt, General Obi-Wan Kenobi fighting Greivous, Cad Bane, and a clone trooper in battle. It's at clone wars.com.
Asajj Ventress's fate is unknown
yes, he's the one with the phase 2 armor that asajj ventress kills with her lightsaber while choking him
Echo did not die in clone wars he showed up in season seven
No she doesn't. But she did somewhat "disappear" shortly before "Revenge of the Sith" took place. To learn more about it, follow the related link below.
No she does not. We never find out what really happens to her. All we know is that shortly before Episode 3 Anakin severly injures her and she is put on a medical ship. The Jedi believe she is dead. But while on the ship she tells the pilot to take her as far away from the war as possible after that she is never heard from again.
No, he does not I have not seen the whole Season 5 but he is probably busy in that Season after all he is an ARC trooper. He is in a Season 6 trailer and that means he couldn't have died.
No
Dengar didn't die in The Clone Wars. You might have it confused with someone else

No, he is alive in episode 3, so he must live through the clone wars.
