Must I hand in the exercise books? No, you needn't . No, you don't have to. No, you don't need to. Are they all right?

By the way, 'Do I have to hand in the exercise books.' Can I answer it with above three answers ?

Yes, they are completely equivalent.

Is 'don't need to' completely equivalent to ' don't have to'?

I agree with the other person, needn't is not widely used here, however, it is not hard to understand either. So, I would encourage you to use it, you inspire others to use it from time to time, lol!

Yes you could answer the question with those three answers, but the first one, 'No, you needn't.' Sounds strange and old-fashioned, at least in American English. I suspect it might be fine in British English.

All 3 are fine, although "needn't" is very uncommon in the U.S., I don't know how it is in other countries.
