So is Hell really forever?

If I died without repenting and went to hell, then Can’t I just go to heaven just by repenting in hell?

What happened to Adam and Eve who didn't repent nor believed in Jesus Christ because he wasn't born yet? Catholics said Adam and Eve are in purgatory. But Purgatory is in Hell. correct?

Jesus went to hell, and then ascended to Earth and then ascended to heaven. How do you explain that?

If you died you can still repent before going to hell, but you can’t repent when you’re there.
