No, he is peak human. Odin stripped him of all his powers and superhuman strength turning him into a mortal form the same as the humans he was amongst. He’s still strong because he still has his muscular build, and obviously his combat training and experience, but no he isn’t superhuman the film made that very clear.
As for the bifrost argument, I guess that makes Jane superhuman too for travelling through it
As strong as a fit human of his size can be. Hemsworth was pretty big in that film, so big that the director apparently told him to get a little smaller for the costume to fit
If he were even a tow tier superhuman like MCU super soldiers, he wouldn't get KOed by a taser or struggle with a 3-4 guys in the hospital. He beat the shield agents using both stats and skill. Depowering Thor shouldn't necessarily take away his skill
