I would think the giraffe would win. Even though the rhino is powerful, it is not very fast. For a lion, getting kicked by a full grown giraffe is usually fatal, and despite the rhino's protective coating, the giraffe would see it, and be ready for attack.
The gorilla can win by its ability to move well and climbing trees. A rhino's charge and horn will crush the gorilla to death if the gorilla does not escape fast. A rhino has thick, tough skin and a good defensive body weight to protect itself. The rhino will need only to bash and flip the monster with the horn. The gorilla will have no chance with the rhino even if the monster attacked first because the rhino will stab the monster to death.
In a fight? The rhino.
A rhino could flip a gorilla
The Rhino would win. The Rhino can knock the Buffalo with his horn and Rhino are stronger than Buffalo.

triceratops
The Thing.

Giraffe by miles.
bear

Rhino! an ape is much smaller, and has no defences
Most likely a rhino when the rhino knocks the lion out with its big horns.
