Thor wins this, adapted Zod might give him some trouble, but this version of MCU Thor is too much for these two guys. The only DCEU Kryptonians who can arguably win against him are Clark and DD. The rest don't have the feats to contend.
Achilles should win. He is not going to let Bucky get in range to connect with a knife when he has the range advantage. Achilles might be on a slight disadvantage in strength, but it is a lot less than people think. He not only has the spear throw feat, he also showed strong enough to literally push Hector with his sword, without loosing momentum, nor posture at all, and Hector was no slouch in strength, or skill. Achilles is faster and more skilled, that's Bucky's downfall in this scenario.
