Yes but you can if you want to save inputs put them all on the same input X,Y & Z Axis.

The switch's 3 terminals would go something like this:
Terminal 1 = input
Terminal 2= output normaly closed or Terminal 3= output normally open.
To check which is which just use a multimeter set to continuity then probe between pin 1 and any of the others, one should show continuity when switch is NOT pressed, this is the NC switch, the other will show no continiuty untill switch IS pressed. This the NC switch.

Personally I would wire all the limits in series X,Y & Z to 1 input and the home switch's to another.
