Answer:
Nouns: you, I
Hyperbole: Throw my hand on a blade
Metaphor: I'd catch a grenade for you
Onomatopoeia: ( I suggest if you can, choose another song, onomatopoeia is normally characterized by sounds of things for example if he said Grenades go BOOM that would be onomatopoeia)
Similie: same thing, look for song that use comparative language such as like or as in their metaphors because that's what really makes a simile
