What happens with the protagonists in Rogue One? (major spoilers)

Question

It appears that by the end of Rogue One

that every single one of the protagonists have died: Jyn, Bodhi, Cassian, Andor, Galen, K2, etc. Are there any major characters introduced in the film on the rebel side who survived?

For the purpose of the question, this excludes people who appear in ANH.

Answer 1

They died

All the protagonists died, whether in battle, at the hands of the Death Star, or otherwise.

• Jyn and Cassian:

  The rumbling overwhelmed all other sound. Jyn tightened her grip on Cassian, and he found the strength to hold her. The world grew brighter, emerald at first and then a clean, purifying white. In Jyn’s mind, the cave below the broken hatch was illuminated with the strength of a sun, and then the walls turned to dust and there was no longer a cave but only her spirit and heart and everything she had ever been: the daughter of Galen and Lyra and Saw, the angry fighter and the shattered prisoner and the champion and the friend.

  Soon all those things, too, burned away, and Jyn Erso—finally at peace—became one with the Force.

• Bodhi:

  Bodhi Rook heard the ring of metal once, twice, in the cabin, and then the soft clatter of something rolling across the deck. He turned in time to glimpse the detonator. He heard nothing as the cabin flared impossibly bright.

  Like a pilot should, he died with his ship.

• K-2:

  With approximately three seconds until total shutdown, K-2SO listened to Cassian’s voice cry his name one last time. Then, without regret, the droid turned his weapon on the console. The comm cut out. With the controls now reduced to a melted plastoid-metal compound, the stormtroopers would have considerable difficulty entering the vault.

  With one second left until total shutdown, K-2SO chose to mentally simulate an impossible scenario in which Cassian Andor escaped alive.

  The simulation pleased him.

• Chirrut:

  The words of the chant echoed in Chirrut Îmwe’s heart once more before he died: I am one with the Force and the Force is with me.

• Baze:

  When death had come for him in the shadow of the walker, he had faced it with defiance. Now there was grief.

  There was no fear.

  Baze Malbus died in pain, but it did not last long.

And so forth.

Answer 2

Sure, depending on who you count. General Draven and Admiral Raddus were both created for the film and survived (at least as far as I can recall). General Syndulla (Hera Syndulla from SW: Rebels) was mentioned on film, which may be counted by some as an "introduction" and seemingly her ship, the Ghost, survived (presumably therefore with her on it).
