Home switches are located X right hand side, Y front, Z top.
Does not matter at all, it can be set in LinuxCNC however you have it and need it.

For Z for example, is this 0 at the top and homing at the top??
Yes, that is correct.

It depends on the machine. Most vmc's home table full front and right so tool changes occur with work/setups/rotary 4th axis etc clear of any ATC motion.

My machine is setup same as they probe_basic.ini in the sim. Homes z up, table right, table front.

It could be also that your axis motors are turning the wrong direction of things aren't making sense.

Ok, so my Z is configured correctly with 0 top and negative moving down as Z+ is top and Z- is down correct? Or should I change some of the config values?

I need to adjust X so zeroing on left edge of table. So will swap zero and set to left edge. I can do that. And Y, I could zero front edge of table (moving to rear) just made me a little concerned as no limit switch and crash would be at back. Wanted limit switch on moving backwards. Any thoughts on this aspect...

I zero y table moving full front and sets zero. travel directions will always remain the same in the Cartesian coordinate system.

Back to the centre home position, you touch off using G54 offsets to achieve this in the work piece
linuxcnc.org/docs/2.4/html/gcode_coordinates.html
Here is an example part where you would touch off on the centre of the part as everything needs to be concentric of the centre bore.
 
This does not affect the machine home position
