Storm is a triggered ability that functions on the stack. “Storm” means “When you cast this spell, copy it for each other spell that was cast before it this turn. If the spell has any targets, you may choose new targets for any of the copies.”
Storm
If a spell has multiple instances of storm, each triggers separately.
When casting a spell bestowed, only its characteristics as modified by the bestow ability are evaluated to determine if it can be cast.
Rulings
Any abilities that trigger during the resolution of Mass Polymorph (such as a creature's "enters" ability) will wait to be put onto the stack until Mass Polymorph finishes resolving. The player whose turn it is will put all of their triggered abilities on the stack in any order, then each other player in turn order will do the same. (The last ability put on the stack will be the first one that resolves.)
All creatures you put onto the battlefield with Mass Polymorph enter at the same time.
If the number of creatures you exile is greater than the number of creature cards remaining in your library, you'll wind up revealing your entire library, putting all creature cards revealed that way onto the battlefield, then shuffling your library.
The creatures you exile with Mass Polymorph remain exiled for the rest of the game.
