My guesses: (only applicable for the battle..after that, all bets are off).
Jon – Alive, but there will be doubt (fell from dragon and yet to be found at the end?)
Sansa – Dead. Undead break through to crypt, she dies leading the defense.
Arya – Alive
Bran – Dead. He and the night king are linked, and harry potteresc linkage, he must die in order to completely kill the night king.
Theon – Alive...Say what you like about him, but he's a survivor.
Edd – Probably dead. I'd like him to live, but let's face it, he's very disposable.
Sam – Lives. George RR Martin says Sam is him...He'll survive the series.
Gilly – Dead Crypt defence.
Little Sam – Alive.
Tormund – Alive...provides colour/contrast and will be interesting when they go south.
Brienne – Alive
The Hound – Alive.
Beric – Dead.
Dany – Alive; Has to face up to Cersei.
Jorah – Dies...heroically of course, probably saving Lady Mormont.
Lady Mormont – Alive;
Greyworm – Alive;
Missandei – Dead; In the crypt, protecting the very kids who shunned her.
Varys – Alive...but not for long...See bonus...Somehow, they will be his death but not this ep.
Tyrion – Alive.
Davos – Dead. For a guy who can't fight, he's pushed his luck far enough already. I'd like him to live though.
Poderick – Alive.
Gendry – Alive;
Night King – Dead; they'll push it to the limit, but he pretty must has to die.
Jamie - Dead...I think he should face Cersei again, and I'd love to see him catch up with Bron, but he'll sacrifice himself in an act of redemption saving someone. Bran commented that he needs to be there and do something.
Bonus...
Melisandre/Red woman...Dead. She left to gather her forces to help in this fight....Expect a force of flame sword wielding lord of light fanatics to turn up at an opportune time during the battle. But having done that, she's done her job and (finally) dies.
