Answer 1

PREFACE:
For -er verb, the "tu" imperative form is to remove the s from the indicative, e.g.:
Tu manges -> Mange!
Tu danses -> Danse!
For -ir and -re verb, if the indicative form does not end with -es, just use the indicative, e.g.:
Tu vends -> Vends!
Tu lis -> Lis!
For -ir and -re verb whose indicative form ends with -es, remove the s, e.g.
Tu ouvres -> Ouvre!
For avoir, être, savoir and vouloir, use the subjunctive form instead of the indicative then follow the above rules:
Que tu aies -> Aie!
Que tu sois -> Sois!
Que tu saches -> Sache!
Que tu veuilles -> Veuille!

5: S'en aller is a set phrase, so first one eliminated. Remove s from indicative, so second one eliminated.
6: The second one and the third one don't make sense at all.
7: The first one is wrong; the third and fourth one is logically incorrect.
8: The second one and the third one don't make sense at all.
9: Être is an irregular verb, first one eliminated; Sois is singular, second one eliminated.
