What does Detect Magic show for different Warlock special weapons?

For reference, Detect Magic snippet:

you can use your action to see a faint aura around any visible creature or object in the area that bears magic, and you learn its school of magic, if any.

Warlocks have a few unique weapon options. I am interested in what exactly does Detect Magic show for the following?

  1. A weapon created via the basic Pact of the Blade feature
  2. Magic weapon transformed to Pact of the Blade weapon (via the ritual), compared to before the ritual
  3. Pact of the Blade’s Improved Pact Weapon (feat) and its created weapon with +1 to hit and damage
  4. Hexblade’s chosen weapon, by touching a normal weapon after a long rest
  5. Hexblade’s chosen weapon, by touching a magical weapon after a long rest, compared to before choosing it

(Meta-note: I could make this 5 separate questions, but I think answer is so short, that it’s better to have this all in one place. But let me know if I really should split it up.)
