1. However long he would be staying, it would only jeopardize his PR status and citizenship, not yours. Staying longer than 6 months might create some problems if the stay is less than a year.
2. Staying longer than a year but less than 2 years will inevitably create serious and most of the time not overcome-able problems if reentry permit had not been secured, and might still create problems even if it was. All of these for him of course, not for you.
3. Same as 2. but this time it would apply to you as well as him.
4. read 2. carefully.
5. Nope. Not at all.
