DCnu Darkseid, no avatar or cosmic hijinkery, his physical team wrecker self. This is a purely physical fist to face question.
Darkseid would stand fast, characters would get one free shot.
Superman (any version)
Thor (any version)
The Hulk (any version)
Sentry
Gladiator
Thanos
Hyperion ( any version )
Captain Marvel (Shazam)
Juggernaut (any version)
Orion
Black Adam
Blue Marvel
I would think it would be possible. For instance, PC Superman has feats like "casually towing dozens and dozens of planets through space". I'm pretty sure that type of strength would KO Nu Darkseid in one hit. At least I think it would, I don't think he's ever been hit with that much power in one hit given nobody in current DC has that much power to begin with. Well, at least certainly nobody Darkseid has fought.
Oh, Pre Crisis Darkseid could casually one shot Nu'Seid.

It's really too soon to know the answer of to this question. So far, none of the characters mentioned are able to do it. Later we may find out that even a Galactus level character may not be able to do so either, so yeah it's a little too soon.
Based off what we've seen Darkseid endure (Powergirl rocked him a little), these people could do it imo...
King Thor
WBH
Wouldn't be surprised if Death Sentry could it based off what he has done.
Cosmic Cube Thanos
Universes pushing Hyperion (using him at his highest. On average, no).
Captain Marvel that fought Spectre.
Trion Juggernaut
