Aux Switch Ground Questions

Hi all,
I've been searching for this, but I must not be typing in the correct search terms.

Three questions:
1. Can you ground all 5 aux switches to the "Chassis Ground BK" plug?
2. If so, what is the load limit (amps) for the ground wire?
3. I have my self-installed front camera on one of the switches. If I put in a light bar and ground them together, would it likely cause interference with the camera? Should I isolate them?

Electrical science is not my forte. Hats off to electricians.

Thanks.

Why not just ground one of the negative terminals of each accessory to its mounting location? Only one wire to run to the aux switch.

Well I assumed the ground wire hookup helped provide some protection to the truck electronics. In my old truck splicing into the wires threw the TPMS code. I was trying to avoid CELs.
