Danys definitely going to die. That's been foreshadowed in the show already when Dario told her she was a conqueror, implying she would never rule.
Jon is going to die because he doesn't want to live. He puts himself in reckless situations not because he doesn't see the danger but because he wants it all to stop. As Berrick said they would find little joy in this life.
Arya will die. There is no place for a loose cannon rogue faceless man picking their own targets. In the books it's even been foreshadowed she will be found frozen to death clutching Needle.
Sansa has said repeatedly no one can protect anyone so my bets on her dying in Winterfell.
After White Walkers are defeated Bran serves no purpose. Its said he will fly but never walk, so unless this means the crows he wargs into to track the army of the dead progress he may well warg into a bird on his death.
Jamie, Cersei, Tyrion and Varys all relics of a bygone age.
Euron is just mad and will get taken out eventually but not before he's killed Theon and Yara, possibly burning their bodies and displaying them like Theon did to fake Bran and Rickon.
Gendry has made a big thing about being Roberts last bastard so Varys may have him bumped off to ensure Danaerys and any offspring may rule.
The only question left is will Dany be successful in her plan to break the wheel, or with everyone gone will the successor be doomed to repeat the mistakes of the past.
