Can you identify these stones?

I'm very new to sharpening and know very little about it. I found these stones at a yard sale and picked them up. I'm hoping to learn more about what they are and what kind of restoring they would require.

There's three, the first is smaller and seems to have a fine and extremely fine side. It has a worn-away sticker that still says CARB.

The second is larger and has a two sides of different roughness, one of the sides is red. It looks very pockmarked and I wonder if it is still useable.

And the third is yellowish and feels smooth to me.

I threw my K55 in there for a size reference:

10497368626


10497583993


10497581743


10497580553


And in case those images don't work...

The set
The first one
The red one
The yellow one

Really appreciate your input & education!

Thanks,
Horace
 
Tough to say from the pics but a guess is that the first one is a combination Caborundum stone (silicone carbide), the second is probably a combination aluminum oxide stone, and the last yellowish one might be an Arkansas stone. If you can get your hands on some valve lapping compound or similar (reel mower grit) or just use a smooth sidewalk and lots of water - you could lap them all flat and clean it would be a lot easier to tell what you have. Looks like some good stones with a little work to clean them up.

If you're anywhere near a home depot, they sell a big combination stone in the tile dept - believe its called a tile rubbing stone. Put some silicon carbide grit or even blasting sand on that with a load of dishsoap and some water. It'll scrub a nice, fresh surface in no time. I all reality, you could use sand and just rub the two stones against each other, again, with lots of water or soapy water, and then you don't have to buy anything. Swap the stones end for end and vary your pattern - use figure 8s mostly. They'll clean right up.
