so I have an HD74S74AP shift register and I'm wondering if you can use this as the 74CHC595 shift register because I see all of these projects with the 74CHC595 and not the one I have. And if it does work as the 74CHC595, can you suggest some projects?

Do you have a datasheet for that part?
HD74S74AP shift register
A HD74S74AP is not a shift register it is a Dual Positive-Edge-Triggered D Flip-Flops with Preset, Clear, and complementary outputs.
If you know how to wire it up you can make a 2 stage shift register. So it will take you 2 Arduino pins to get 2 shift register output pins. A total waste of time.
