What is the maximum number of scholarships any one person can receive for college?

You can get as much as you have left for unmet need. If you have no unmet need left, you can sometimes replace some loans with scholarships. Unfortuanetly, sometimes winning a lot of outside scholarship money effects the financial aid package for the college.

You can apply to multiple scholarships through websites like SchooLinks. They allow students to apply to multiple scholarships, which have similar questions/prompts, in a single application form.
