Yes, lampreys are jawless fish. So are hagfish. Lampreys and hagfish have slender, eel-like bodies without scales. They do not have paired appendages, and, of course, they lack jaws. They have cartilaginous skeletons and often do not have vertebrae.
No, a lamprey doesn't have jaws, it is a blood sucking parasite (no offense to any lampreys out there) that evolutionarily doesn't require jaws, so as a species it selected for animals with smaller and smaller jaws until the jaws in that species were nonexistent.

Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws. See the related link for more information on the primitive jawless fish.
