These figures have been seen before, but one is in packaging that reveals it is not just another clone trooper. The AT-TE is listed as 'Captain Rex', which I'm guessing is another character from the Movies or Cartoon series. I recall Cody from the Movie, but not Rex.

Also shown is the V-19, who is still probably a 'Clone Pilot', but it's packaging isn't shown to verify it.
The Darth Vader looks like a straight repack (minus the mini-figure).
