They do. When I first went through my initial hundred floors, I found the mermaid merchant about a dozen times, the white rabbit about half a dozen times, black alice three times, Nanabi twice, and Sara / Salamander / King of Sabasa / Sea Weed Girl / Neris once. I'm going off memory here so I may be forgetting a few.

The trend I noticed was that a character with multiple services were more likely to spawn than others. White Rabbit and Mermaid Merchant offer a bunch of stuff so I found them the most, Black Alice has three different challenges so I found her a few times. I found Nanabi twice because she has a lot of training to offer while other NPCs only have one service so I didn't see them that often.

Of course, due to artificial randomness, it could just be a coincidence and I got really lucky for finding one NPC several times so there might not be a trend.
