Is this specific to a certain paint gun?

No. You just dip it in the paint and then count how fast it’s running through

What's the diameter of the hole at the bottom of the cup? Amazon is currently sold out but there are similar cups for sale here.

I measure it an 1/8 of an inch or 3.5 mm.

Is this equivalent to a Ford #4 viscosity cup?

Ford viscosity cups are named by the size of the hole diameter. Ford #4 has a 4 mm diameter opening. This product has a 3.5 mm diameter, so it's close but not exact. If you use the times the manufacturer provides you should be fine.
