Rex's fate has not been confirmed yet. So we don't know if he dies or not
He isn't mentioned, no.
Rex's fate has not been revealed.
What clone? Fives, Rex, Echo and Cody are in it and as far as i know the other clone names are unown
Yes, they can. Even though all clone troopers have the same face, they all have different personalities and skills. There was one episode in the Clone Wars show called "The Deserter." In that episode, Rex found a deserter clone who was married and had 2 kids.

[Spoilers] Yes
no the series isn't over unless you are referring to the 2003 series which rex isn't specified
No one knows what Rex's fate is. But I don't think so
No, he is alive in episode 3, so he must live through the clone wars.
Echo did not die in clone wars he showed up in season seven
"Orders"
First off, your question is a bit pointless at the beginning. Rex does NOT die in the pilot film since he is in the series. And Rex's fate has not been confirmed yet.
