1) You are joking, arent you?

4) Dont forget to call me, will you? This question is uncorrected.

5) When is the film starts? This question is uncorrected. The mistake is the auxiliary verb. We must use does in Present Indefinite and we dont add the suffix s to verb in Interrogative sentences.

6) Does the clothes fit you well? This question is uncorrected. The mistake is the auxiliary verb. Clothes in plural. We must use do with the third person plural.
