Izzet Staticaster’s activated ability has only one target. Other creatures with that name are not targeted. For example, a creature with hexproof will be dealt damage if it has the same name as the target creature.

The name of a creature token is the same as its creature types unless the token is a copy of another creature or the effect that created the token specifically gives it a different name. For example, a 3/3 Centaur creature token is named “Centaur.”
