ausamsam,
Are you legally eligible for employment in the United States? If not an American Citizen, provide I-9 certification.
Yes if you have a valid work permit like OPT
Are you an alien authorized to work in the U.S.?
How should we answer this?

Can I (or all F-1 students) use this form
Yes you can if your employers ask you to fill it. They would tell you and give all forms you need. So don't worry.
For H1, can we work as part time? Like adjunct Professor/instructor?
Yes you can.
I recently saw this in a job application. If a company/college asks for this, how do I know they would like to sponsor for visa?
You negotiate and discuss it with them after they express intent to hire you.
How do I check?
Ask them when they express interest in you.
