The difference between a Champion and a Special is that Champions are the fighters themselves, collected through Gacha systems, while Specials are combat abilities like Grimoires or Stands that a Champion can equip and use in battle.

Quirks are generally the hardest Special type to get, dropping at roughly a 1% rate from boss fights or gacha spins, followed closely by Stands at around 1.5%.

No, Bloodlines and Armaments aren't part of the original five Special types, they were added later as additional categories alongside Grimoires, Devil Fruits, Kagunes, Stands, and Quirks.

Yes, you keep the Champions, Specials, and Auras included with my purchase, exactly as shown in the listing.
