English is not my mother language but I will tell you my opinion!
1."There is a hammer and a screwdriver in the car."This sentence is correct! We can also say "There are a hammer and a screwdriver in the car."This sentence sounds awkward because the noun " a hammer "that follows " there are " is singular!In this case it's better to use " is".Some language commentators still insist on using "are" in sentences like this despite the awkwardness.
2."There is a hammer and two screwdrivers in the car."This sentence is correct! We can also say "There are a hammer and two screwdrivers in the car."Some language commentators still insist on using" are" in sentences like this despite the awkwardness.
3."There are two screwdrivers and a hammer in the car."This sentence is correct!
4."There are computers and two desks in my room."This sentence is correct!
5."There are two computers, a desk, and a sofa in my room."This sentence is correct!
Yes, there's is informal for there is. In very casual speech it might also be used for there are.
Preferred by whom? There's is certainly not preferred in correct speech, but it is widely used in informal conversation.
There are is correct when speaking of more than one item, though we might well use there's in informal speech.
