Yes
for natural teeth, most people have a set of baby or milk teeth first. When these fall out as the adult teeth grow in.Some rare cases of multiple rows of teeth have been noted. Loss of the set of adult teeth may require full or partial artificial sets of teeth or dentures. These can be replaces many times.
Rare as hen's teeth
Yes, it is true that some people lie just to get attention. But, there are some people that actually do have anywhere between one to seven pair of adult teeth. I myself am one of those people. I have to have one of the third set pulled. And trust me if you are one who doesn't have this your lucky because it hurts. Sometimes the teeth come trough your gums instead of pushing your other teeth out. But don't worry about having this only 1 and 200 people have this.
Third molar teeth (Wisdom Teeth) consist of the madibular and maxillary third molars
third molars
Yes they do, all teeth have a second set of teeth

No, wisdom teeth cannot replace molars in the mouth. Wisdom teeth are a third set of molars that typically erupt in late adolescence or early adulthood, but they do not serve as replacements for missing or extracted molars.
Yes, cervids have a set of deciduous ('milk') teeth before their permanent teeth erupt. The upper teeth are first composed of a second, a third and a fourth premolar. They are then substituted by a permanent second, third and fourth premolars and molars 1, 2 and 3. They also develop two canines on the upper part. In the lower part, a deciduous second, third and fourth premolars are subistuted by permanent second, third and fourth premolars, a first, second and third molars. They also shed deciduous incisors one, two and three as well as a canine, and are then subsistuted by permanent ones. A good book on the matter is 'Teeth' by Simon Hillson (first and second editions) published by Cambridge University Press.
Horses lose their deciduous or "baby" teeth. When horses are born they already have their secondary set of teeth underneath their "baby teeth" just as humans do. The permanent set of teeth will grow in and push the primary set of teeth out.
