Well lets say a Grizzly Bear against a giant green anaconda then it would go to the bear as long as the bear could see it. Same with the Black Bear. A sun bear,Panda Bear,Or spectacled bear would loose no doubt and the polar bear would kill the anaconda in seconds. In the water a large enough anaconda would be able to kill a brown bear or black bear if it could ambush. The anaconda would be no match for a polar bear.
Hyena wins on land. The anaconda would be too slow and sluggish on land to do anything. It would have about zero chance to catch the hyena. One bite of the hyena can crush the anaconda.
Anaconda wins in water. They are very fast in water and can ambush attack. Once it coils around the hyena, the fight is over. Hyenas are not good swimmers.
a tiger would win
