are any of the gears 10/77 tooth and 2-1/16” diameter?

largest Gear in this 58pc bunch is 1.14" or about 30mm nothing larger,

What diameter axle is needed for these?

It varies - more or less 0.5 mm to 1 mm. I needed a press fit so I drilled one out until it was a tight fit on the shaft.

HOw many of these gears can interlink with each other ?

They are all supposed to be module 0.5, so they should all work with each other. I tried a bunch at random, and this seemed to be true.
