Coalition Fee Waiver?

So basically my family just misses the requirement for the Free and Reduced Lunch Program, but I believe that we are pell eligible as our income isn’t high and I have an older brother who is in college as well (I put our numbers into the FAFSA calculator and it says that I’m eligible). My question is how does Coalition work with checking if you’re pell eligible? Because my brother wasn’t eligible last year but our finances and circumstances have changed since then, but I don’t want to apply to all these schools if something goes wrong and I end up not being pell eligible. Also, is there a limit to the number of schools I can apply with the fee waiver?
