Answer 1

4. Who is the subject but in this sentence you is the subject. Whom is the objective case and that's what you need here. It's best to NOT end a sentence with a preposition. Who did you stay in the mountains with? = With whom did you stay in the mountains?

7. Same type of error as #4 with who/whom. Who did you invite to your party? = Whom did you invite...

14. (or set?) = no, don't use that

Everything else looks good!
