Yes that should be ok. With the note that 1.2A is more of a minimum, something like 1.5-2.0A would be sort of better. Although in practice with the pot on the driver will probably adjust current peak to somewhere about 0.7-1.0A.
The power supply of 5A might be inadequate if you want to run 5 steppers and also microcontroller, and other peripherals, it may just not be enough, so dunno about that one.
