@elisabeth7 - You need to check each scholarship individually. Some may be strictly merit-based.
Have you sat down with your parents to run the Net Price Calculators at the websites of some of the places that are currently on your list? What do those calculators indicate your family would be expected to pay? With five children at home, they might be more affordable than your parents think.
If your parents won’t be paying anything, then you need to focus on big-merit institutions. Start with the thread at the top of this forum that lists Automatic Full-tuition and Full-ride scholarships. See which of those you qualify for now, or could qualify for with a slight boost in ACT/SAT/GPA. Some of these scholarships will change for next year, so you need to check on each of them separately. Pay attention to application dates. Admission may have one date, but scholarship consideration may cut off much earlier. Check your own home state public universities too. Some of them have serious merit aid for in-state applicants.
Ask your parents if they will cover your health insurance while you are in college. Will they let you live at home for free if you decide to commute to a local college/university?
