they are the same in size but different in external characteristics
They are the "same" by the fact that they belong in the same Family being Bovidae. However, more specifically, yaks and water buffalo are not the same, actually. Yak and water buffalo are two distinct species of bovids. One lives in Nepal and Mongolia, the other is found in the south and east regions of Asia, like in Taiwan and India.
Yaks are very hairy creatures, with very long hair and a large hump over their shoulders. Water buffalo have very short hair, long horns that splay towards their back, and quite a bit larger than a yak. Water buffalo are found in the tropics, whereas yaks are found in the cold mountainous regions of Nepal and Mongolia.

No. They are not located in the same place. Water buffalo are in Asia and a hyena is in the Africa savanna . If they were together a hyena eats dead animals and if there was a dead water buffalo it would eat it.
