This is the lineup that's alive at the end of Rebirth.
Ignore the flashback panels to previous teams. Timeline was broken at that time so every versions exist at the same time. The timeline's now fixed, but we don't know which of these still exists.
The only confirmed one post Infinite Frontier are Fab Five, NTT, Damian's team (the new gens), and New 52 (Bunker)
Joey and Terra's alive in Deathstroke's team Defiance, but at that time Judas Contract story was replaced by Lazarus Contract. The flashback in the current Nightwing and the age of Beast Boy implied that Judas Contract is back in continuity, and Terra as far as I know hasn't shown up again. So I don't know if anything change there from Rebirth to Infinite Frontier.
Death Metal said Infinite Crisis was canon and Superboy Prime went on a journey of redemption, but currently Bludhaven is still standing so I don't know about Pantha and the others. They're not in the gathering above though.
Anyway, the only confirmed deaths so far are Heroes in Crisis.
