Would observation hours done in high school, count?

I observed a few SLPs during my senior year in high school

As long as you have documentation (signature and ASHA #) to show for them, I would think so? You'd have to ask the schools you're applying to, of course, to be sure, though. I hope they'll let you use them, though.

Are you in high school right now?

I totally agree with Papaya especially since you seem to be on the fast track (I.e. No chance for observations to be expired if they do at all).
