I think the answer is "each other" for all of them?
Hi there here are the answers
1.Our school principal visited our class today
2.All students will take the test next week
3 The math teacher surprised all of us
4.That is my favorite notebook
5. Today is a holiday
6.I saw Mr.Clarke yesterday

also the beginning letter of each sentence must ALWAYS be capitalized
