Those are not well-formed expressions in English, so it's hard to figure out what grammar the translation should use. The first one probably means "King of the Elf-friends" but I can't really make sense of the second one ("friend of the king of the Elves", "friend of the king, who is an Elf", "king who is an Elf-friend"?).
