Missing bits on my car

Hi all

Just a question, I need another one of these…but have no idea what its called…

Also on the other side(being drivers side) i have this massive space!!

Any ideas on what replacements i should be ordering??

I have ordered engine under cover, both wheel arches ! What else do I need please?
I am determined to get my dads car through winter

Thank you

The first photo is the screen wash bottle cover I think. Is it an ABS model?

Can’t really tell what’s missing from the other side apart from a support bar that runs from the bottom of the bumper to the front of the chassis leg.

Edit: actually, it looks like the whole intake air guide is missing…
