Isle of Vesuva

If the permanent targeted by the chaos ability isn't destroyed (because it regenerates, or because it has indestructible), all other permanents with the same name as it will still be destroyed.

If an ability of a plane refers to "you," it's referring to whoever the plane's controller is at the time, not to the player that started the game with that plane card in their deck. Many abilities of plane cards affect all players, while many others affect only the planar controller, so read each ability carefully.

As a token is created by Isle of Vesuva's first ability, it checks the printed values of the creature it's copying, as well as any copy effects that have been applied to it. It won't copy counters on the creature, nor will it copy other effects that have changed the creature's power, toughness, types, color, and so on.

The chaos ability will destroy all creatures with the same name as the target creature, not just tokens created by Isle of Vesuva's first ability. It doesn't matter who controls them.

If the creature that caused Isle of Vesuva's first ability to trigger has already left the battlefield by the time the ability resolves, the ability still creates a token. It will have the copiable values of the characteristics of that nontoken creature as it last existed on the battlefield.

A token's name is the same as the creature types listed by the effect that created it, unless the token copies a permanent or that effect specifically gives that token a name. For example, the effect of The Fourth Sphere's chaos ability creates a token with the name "Zombie."
