I had this same question some time ago. As stated in the text, the 5 Nazgul withdrew after stabbing Frodo, thinking he would have soon succumbed to the wound. This suggests of course that they had some experience in the matter of turning their victims in to wraiths. This suggests in turn that there are more than one of these victims wandering around, although lacking one of the Nine Rings, there power would be very limited.
In fact, I was wondering whether this was not the fate of Earnur, who was lost in Minas Morgul...
