No. They're in the same kingdom Animalia, phylum Chordata, class Mammalia, and order Perissodactyla. But horses are in the Equidae family, and rhinoceros in the Rhinocerotidae.
no, but i believe that they may be distantly related to elephants
Rhinos are NOT in the same family as horses and they may have been the cause of many "real" unicorn sightings.
I'm not entirely sure what the question here is, but the rhino and the horse are in the same order, Perissodactyla, but not in the same family. And yes, that is one theory on the myth of the unicorn.
Rhinos are scientifically placed in the group of pachyderm. but people once thought of them in the same familly as horses in error. It is possible they inspired the unicorn myth but it is unlikely, since they look so different.
No they are not from the same family, sea horses are a special kind of fish, horses are mammals.
No
Horses, yes.
The closest relatives to the rhinos are the Tapirs and the horses. I have no idea why thou!!
Rhinocerotidae.

Rhinos belong to the family Rhinocerotidae, within the order Perissodactyla, which includes other hoofed mammals like horses and tapirs. There are five species of rhinos: white rhinoceros, black rhinoceros, Indian rhinoceros, Javan rhinoceros, and Sumatran rhinoceros.
Paint them the same color as other rhinos.
