Answer 1

1. As a date, you can say twenty twenty-five, but as a regular number, it's two thousand twenty-five. You don't want the word "and" in there. That word usually indicates a decimal.

2. "In the year two thousand" is clearer when you are indicating the calendar year.

3. Your second sentence is correct.

4. http://www.englisch-hilfen.de/en/words/which_what.htm

5. Either works fine; they mean the same thing.

6. "How long..." is better, smoother.

7. Either question is fine; the second is smoother.
