gorilla
The panther will not win since the gorilla will give a strong blow to the panther and the large ox will knock down the panther with its head. This leaves the large ox and the gorilla together in fighting. The large ox will win if it knocked the gorilla down with its head or at least gore it to death.
Probably the gorilla, as cougars do not like to fight an animal that will stand up to it and be prepared to fight it.
gorilla
The gorilla is most likely the winner. It is likely that the small ox will not win because the panther can kill the small ox by biting or clawing it and the gorilla will throw a stone on the small ox's head. The gorilla later will beat the panther by a snap on the throat or throwing a stone.
A male gorilla is typically much larger than a male kangaroo. While a kangaroo's kick can disembowel, a gorilla's heavier frame and ability to grapple an opponent would likely carry the day for it.
a silver back gorilla would win easily win!
Possibly the gorilla, but fights between these animals are extremely rare.
Elephant .
The gorilla can win because of his mobility but likely the elephant unless the gorilla is smarter then the average gorilla. The elephant just needs a few pounces or 1 charge to win but the gorilla needs to be quick and persistent which is harder to do in a fight so my moneys on the elephant.

Probably the gorilla, unless the small man was armed with a gun.

The gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
