it says expiration date 5/2021 , are they still usable?

Probably, they are dry reagents. I would suggest ordering a new batch, comparing tests, and then decide.

So just to confirm hi774 is the same as hi736?

Hello hi774 is NOT the same as hi736. HI774-25 is designed to be used with samples that have an expected range of 0.00 to 0.90 ppm phosphate. HI736-25 is designed to be used with samples that have an expected range of 0 to 200 ppb phosphorus.
