Curiosity Shop Man vs Gorman outcome: Frankly this match serves no purpose since one can't really say who has a better advantage over the other character. They both don't have any weapons in their possession. If you think about it, both are considered to be pacifists since they don't revolve around fighting situations.
Link vs Deku King & Guards outcome: Well you played Ocarina of Time, you would know that Link is capable of destroying Deku Scrubs, thus it is possible that Link is able to take down the Deku King and his guards. Like with the previous match you posted, the Deku King and guards don't seem like a fighting race since they only want for their race to be safe from their surroundings.
Sakon vs Bomb Shop Man outcome: Likewise with the first match, there is no advantage that one of them has to take on the other. While Sakon may seem to be the type to use weapons, he's just a thief and only wants to get his unfair share in prices. Bomb Shop Man does have bombs in his possession, but he only plans to sell them to those that are interested in his product.
Ganondorf vs Sakon, Zora, Darmani outcome: Judging by the capabilities that Ganondorf was able to do throughout the series, there is no doubt that his powers surpases those of Sakon, Zora, and Darmani combined. Though it sounds bad, but there is no way that unlikely trio could ever beat the King of Evil.
