I don’t usually pay too much attention to these two cymbiformis, but the other day I noticed these lines of raised bumps on their leaves. I immediately was worried about mites, and I promptly quarantined the two plants which had been with all the others. Does this look like mite damage and if so, would the rest of my plants be considered infested? Should I treat all my plants just to be safe?

I’m not saying that it’s not mites, because I’m not exactly sure what that mite damage looks like, but that looks more like edema to me. Like plant cells swelling with water right before they burst and leave scars, but that’s just a guess.
Those raised green bumps don’t scream mite damage to me. Neither do the vertical lines because they aren’t raised.
However, you see any raise vertical lines that run diagonally across that same area of leaf tissue? That would be alarming to me.
I don’t know about the dark green bumps, but the lines along which the bumps appear (most noticeable in the center circle) do look like mite damage to me.
If you have access to a microscope (even a cheap one will do), use a piece of matte Scotch tape to pick up “dust” from along those lines. Examine under the microscope for mites.
If you find dead mites, but no living mites, it could be that the seller already treated the plant. But watch the new leaves for more damage as they come in.
