Can Darkseid take a bloodlusted sucker punch from Thanos

Yep.

Yes, but since it is a sucker punch, I couldnt answer "without a scratch." I think Darkseid is Thanos' superior, but its not such a big difference that Thanos couldnt cause MAJOR damage.

Sucker punch counts as The Pimp Hand?

Nevertheless, Darkseid is durable enough to take a blow from the mad titan

Actually, I do want to know which version of Darkseid specifically this is, as his powers are all over the place. The final Pre-52 version was a Multiversal threat. The New-52 version is a team buster, but seemingly something of a mindless hulk. Other Pre-52 versions could be beat by heralds. Etc

They are equals. He could take the punch from Thanos and vice versa. Starlin openly states Darkseid as the inspiration for Thanos.

They are equals, but Thanos has edge in intellect.

Even though I accidentally voted no, the answer is yes.

Yep and like a BOSS
