My guess is that none of the USS Arizona survivors were below decks when the ship was hit. All of the others were cremated.
No, the destruction was primarily forward. Many survived from the after spaces, though many were badly burned as well.
A recent NOVA (I think) show covered a project to explore the interior of the Arizona with a remote camera drone...the spaces they explored were remarkably intact. One of them (far aft, maybe Admiral Kidd’s quarters?) showed an intact dress uniform still hanging on the wall.
