I can only list 5 awards. Which of these should I list?

Try to understand what’s important and what “order of importance” means. Unless they offer NMF merit awards, that’s based on PSAT and they aren’t concerned with that test. If you choose to include it, make that your own decision. If you submit your AP scores, they know what gets Scholar awards.

In the past, CC posters have suggested a hierarcy: national, then area or local, then hs.

Do what you like. But please, try to understand. You want to be in control of your own app, you want to know, whether you win or lose, that this was your best effort. Not crowdsourcing.
