I also do not know which stones on the turn box set are fine and which ones are medium.

I have the same question! It should be in the instructions.

In regard to the quesions above:
I didn't check my Turnbox package for stone grit descriptions, but here's how it goes generally with every alumina ceramic sharpening equipment. The white/lighter coloured rods can be either fine or ultrafine grit (the latter one being just a polished fine stone). The brown/grey/darker coloured rods ale always medium grit.
Here's the main difference betwen both types of rods. The white rods have closed pores (they are smoother to the touch), so they cut less aggresively/slower and almost don't wear out. The brown rods have open pores (they are rougher), cut more aggresively/faster and slowly wear out over time.
Hope this clarifies the general differences a little bit.
