Financial aid

Hi, I’m a sophomore in high school, I live in Illinois with my mom and my two brothers who are both off at college. My mom makes about $30,000 a year which isn’t a lot so I was just wondering about how much money I could possibly get in financial aid. I know that there are a lot of factors that play a role in the amount but is there a maximum amount that can be given? Also how much money can I take out in student loan? Once I take out this money do I have a lot of time to pay it back? Are a lot more scholarships available for lower incomed people? Just a few general questions, thank you so much!
