================================
Are the sentences or directions above grammatical? Please correct some errors. Thank you.

Answer 1

2-2 -- I'd say "on Team 2" but using "in" is not incorrect. And you can either use "the" or omit it. The sentence is clear both ways.

5 -- No team number is indicated.

Otherwise, everything reads just fine.
