I'm building a DIY CNC router.
Can I use a 24v-5A for my nema17 stepper motor? my motor says it needs a 1.2A per coil
and I'm using four A4988 stepper driver with an Arduino and a CNC shield v3.

You can use a 24v supply. You just have to set the current limiter on the A4988 to not go over 1.2A. There are lots of tutorials out there on how to do that. Just google "setting vref on A4988".
