Basically, what Ren, Fox, and perhaps Arslan did is kinda like those martial arts styles where the people who practice it say that you are channeling your chi into your hand. It's things like that, that supposedly make the one inch punch possible. You're not just hitting them with your hand, you're also hitting them with the force of your chi. Or something.

That "more than just a man" thing is theorized to have something to do with Ozpin not following the CNR (as Monty says, though people have objected that) despite the CNR becoming a thing 80 years ago. After all, the video showed a silhouette of Ozpin at that part.

Really, I think he has trained his Aura up to be so powerful that he has it repeatedly heal his body so that it doesn't wear out, thus slowing or stopping the process of aging. This would also be why Monty said that Ozpin is super powerful, though he only gets involved in something when he absolutely has to. Monty himself even said that Ozpin is "an old man" and "old as dirt." Now, that's not to say he meant Ozpin is literally ancient. By "old as dirt," he meant "old as fuck"/"old as hell."
