student 1: Anne- marie et benjamin viennent-ils?
student 2: non, ils ne viennent pas.
Explanation: keep doing that for the rest when asking the question just put the person name and then the verb "venir" but don't put the pronoun make sure that you have the right ending, for the student 2 part just put "oui" if they're coming, put "non" and also "ne, pas" if their not going and then replace the names with a corresponding pronoun.
