Yes, 1 is American English and 2 is British English.
None of the rest are normally used in English, British or American. Here are some that would be:
He's serious, isn't he?
She's a kind person, isn't she?
They work very hard, don't they? (sub for "diligent")
The tag question is asked about the person(s) being described, not the person with the opinion.
1. John has a book, doesn't he?
2. John has a book, hasn't he?
---------------------
Is #2 used in British English?
===============================
3. I think he is serious, isn't he?
4. I know he is kind, isn't he?
5. I believe she isn't diligent, is she?
6. I think he is serious, don't I?
7. I know he is kind, don't I?
8. I believe she isn't diligent, don't I?
(What about these ones? Which ones are correct?)
