Pups like Loki seem to have endless energy & that's pretty normal. Does he know the "stay" command? Does Zeke & Clover?
When you want to sit to watch a movie or whatever, put Loki in a sit/ stay or down/ stay. When he "stays" in a sit or a down, reward
him with a good chew toy. Something to keep him busy while you can sit & be with Clover & Zeke for some quiet time.

He may need to be reminded he is expected to stay in one spot with his reward, but he should know you are serious about it.
See if that works for you.
