I can not tell which stone is the fine and which the ultra fine as I lost the red marking.Can you help me ?
Is there a certain way to find the ultra fine for sure?
 
The only difference is the surface finish. Under high magnification you may be able to tell which is smoother
 
Try running a fingernail along the some part of the rod that you do not use for sharpening.

I don't have the rods, but I do have the bench stones, and a fingernail along the side of each stone made the difference clear.
 
I've got the fine & ultra fine triangular Sharpmaker rods & I can "feel" a difference between the 2 when I pull a carbon steel knife (a Chinese cleaver in this case) along the length of each, there being more "drag" on the "fine" as opposed to the "ultrafine" rods.
