The first pic is the nose cone? I'm no expert, but I'd try replacing that since a whole chunk is gone.
2nd pic chin spoiler? If so, looks repairable if that's the worst of it.
3rd pic -

should be repairable as well.
There's special stuff required to fix those plastic bumper pieces - check out eastwood.com or with a local body shop to get it - it's like a 2 part epoxy that stays flexible when dried, yet is sandable. I've never personally used it, as I'm no body work guru.
AND - make sure that motor is PINK when you drop it in, so you can be as cool as I am! In fact, I really think you need to paint the whole car PINK to match!
