There are just too many variables to this question to be able to answer, simply because there are more animals involved than can be justified in a normal "who-would-win" question.
The crocodile could win, but would get badly injured by the ox and the cattlebeast's body.
The gorilla will defeat the cattle-beast easily because the gorilla is more suited when it can stand and grab things.
The gorilla would win on land. It can break the crocodile's jaw or shut it tight. In water, the crocodile would bite the gorilla and drag it underwater.
Some dogs will get the cattlebeast by distracting it and others will go behind to bite out the hamstrings. If the dogs avoided the horns and the hooves, the dogs will get the cattlebeast at the end.
Most likely the gorillas.
The leopard can stand a chance against the crocodile due to the speed, but the crocodile has very tough skin that the leopard cannot bite through. The crocodile will grab the leopard with its jaws and crunch it to death.
crocodile wins
Probably the crocodile.
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 vs Elephant? The Elephant no contest
A polar bear would win the fight on land if it clawed the crocodile's head and flipped its body to claw its stomach. In water, the crocodile would definitely win the fight.
