As for elves, even if they happen to live on a different planet from friends, there's no reason to assume it's the same universe. As far as I know the only cross over between them is a go-kart racing game on mobile. That's not going to be canon.
Now if you want to argue about magic existing in Friends' universe we can talk. Magic is for sure a thing in the Elves' universe, regardless of if you're in elf land or the human world. So if we can pin point a set or even an animated video with magic we can at least make the jump from there. I know we've seen a few stage magic type sets from Friends.
