2) It’s two months since I last saw Mary. Mrs Brown hasn’t seen her son for three months.
3) When did it last snow? In December.

Answer 1

1. You can say what you put in parentheses, but the first phrasing is better ... smoother.

2-4. OK

5. I'd make the answer to this question simply "Eight months" or some other expression of time. The question asks "How long...?" not "When?"
