{Infinite Reflection}

It would 'kill' his legendary creature and all of YOUR nontoken creatures. As the caster of the spell, you control infinite reflection, even if you attached it to an opponent's creature. The "you" or "your" appearing on a card refers to its controller, in this case the caster and not the controller of the creature it's attached to.

[Coffee Vampire]

No, only the one that you made your creatures a copy of, and only if it is legendary. Oh and also all of your creatures would die.
