Landlords can make up any list they want, or any claims they want, but whether or not they are legal is another question. A drip pan under a refrigerator or a liner under a stove are going to wear out over time...
It looks like rust and oxidation, normal aging, and not something caused by your neglect.
These are relatively inexpensive items.
As for your landlord's list, I would consider missing or damaged window screens normal wear & tear. Wind, rain, etc. will cause this, not a tenant's neglect.
