Hillel the Elder and Jesus were contemporaries, according to the stories.

8. There's no way to know, actually.

For anything that far in the past, our information is sketchy and unclear. There are no contemporaneous writings at all that mention Jesus, whose real name would have been Joshua or Yeshua or something like that. None. The gospels were written decades later. Nobody really has any evidence that such a person existed at all. However, it's entirely possible that some person with the name Joshua was rabble-rousing and making a nuisance of himself around that time. He could even have been executed by the Romans, who weren't averse do killing annoying troublemakers.

The rest of the story, however, might contain no actual factual information at all. We cannot and do not know. A few billion people believe the stories to one degree or another, but that's only evidence of their belief, not of the actual facts.

Wherever there are stories of deities and supernatural entities, evidence of their existence is nowhere to be found. That should be a clue to all of us. Stories are not necessarily records of actual events.
