Wiring a stepper wrong won’t hurt the board or stepper, it just won’t move. Start with that wiring order, just keep in mind you might need to change a couple.
You can use the multimeter to check the motor wires coils A+ A-,B+B- by setting continuity test on multimeter
You can search on you tube will be able to find many videos on that
You can touch 2 together and turn the axis if it is harder to turn it’s a pair isn’t that what you need I may have just got lucky also I dont think you can hurt one unless you disassemble it just disconnect power before hooking or disconnecting wires. I hope he figured this out by now though
