Yes (this appllies to most step motor drives with opto-coupler inputs)

Yes.

Yes, you can make a little loop at the drive.
(if you are good with a wire-stripper you can do this with a single piece of wire)
 

Thank you for your times and your kindness PCW. Best regards.

SW3 Set for 5V mode

The ENA, ALM and BRK can be left unconnected

I have a similar setup I'm building. If I wanted to use the ENA and ALM as well as STEP/DIR, which position should the S3 switch be in 5V or 24V? I know the 7i96S provides 5V power for STEP/DIR but my field power is 24V. Can I do this or would I need to provide a separate 5V power source for my ENA/ALM signals?

I would use all 5V signals for the step motor drive interface 
and possibly 24V for limit switches .

How does one go about mixing 24v limit switch inputs with the 5v ENA/ALM inputs?

You can mix  7I96/7I96S input voltages if the inputs are wired in sinking mode,
that is if the input common (TB3 pin 12)  is wired to ground and the sources 
(switches, alarm signals etc) supply a positive voltage relative to this ground,
in this case, the input will respond to positive voltages between 5V and 36V

so
Home/limit switch:

+24V  --> SWITCH COM  --> SWITCH NC --> 7I96S isolated input

 5V alarm signal:

 +5V alarm signal --> 7I96S isolated input

7I96/7i96S input common --> 24V GND and 5V GND

Note the the enable signal is a 7I96S output so can either be driven from a free step/dir output
or an isolated output

Yeah I realized what I said about ENA after I posted. Thanks for the clarification. So, should my prox sensors be NPN or PNP in this case? Crossing fingers for NPN.
