Hello, whenever i go to my friends house i bring my dog with me, he's a 5 year old mixed male dog whom is neutered. He trys to specifically hump 1 out of the 3 other dogs in the household and that dog is a 3 year old male. He's never done this before since Ive gotten him and only does it to this specific dog. Whys that?

It's hard to say why Duke might be doing this with only one specific dog. Humping in dogs is often associated with frustration, over-excitement, or can be an attempt to solicit attention or play in some cases. It would help to be able to observe the dogs interacting in order to make a better guess at why he does this. If it's causing a problem, the best option would be to simply separate Duke from this dog when you are at your friend's house, or keep him on-leash so that he can't bother the other dog. You could also try giving him something special to chew on when he is there, such as a bully stick or rawhide, to help keep him busy.
