I think we're at like a 99% chance of a fairly major character death happening next week.
You're just saying that because seven dudes went after the army of the dead and at least 3 of them are basically redshirts with no real relevance to the plot beyond "named characters who were in Season 3 who can look cool swinging a weapon."
Safe:
The Hound = safe; people want the Mountain confrontation and he's had the full seven seasons without his plot being resolved.
Jonerys Targaryen-Snow = Unbreakable Plot Armor to the point the plot would actually break if he died because nobody else cares about the Zombies.
Jorah = There's no reason to waste 2 seasons and 40 minutes of total airtime on curing his greyscale if he just kicks it here.
Unsafe:
Tormund = Fan favorite who has no real impact on the plot; easy cheap death candidate, but I could see him staying alive if only because the Wildlings literally become irrelevant if he's dead since he's the only named member that is alive.
Gendry = Walking Loose Plot Thread that's now been resolved.
Beric: Nobody cares about this guy and his plot has had like 5 minutes total in the entire series and there's no time to pick it up.
Thoros: Nobody cares about this guy and his plot has had like 5 minutes total in the entire series and there's no time to pick it up.
