Not I, I'm bad with Japanese and bad with low grit stuff. Wild guess on the second, maybe a dalmore? I think the label is the key there. There's a good 3 or 4 words that can probably be made out with some effort.
I can't tell. Maybe the sellers would know? I don't use Jnats much, but I've seen quite a variety of stones being called "Honyama"--maybe check out a dedicated Jnat vendor's site for examples of similar stones. Not sure abut the second one either. Looks kind of sandstone-ish. Maybe Ohio bluestone or a Queer Creek variant? Also depends on where you and the sellers are located. I am assuming a North American location. In Europe, the second one could be something else.
