The hovering coin is definitely bullshit. The positive poles of the batteries aren't even connected, and the spoons are connected together. Even if they weren't and the batteries were in circuit, I doubt the one-turn coil would do anything to the coin with the current in question. Even if it did, the coins behavior is not what I would expect from being placed in a magnetic field from a coil.

The battery with magnets in a coil should work.

The animated stickmen on the spinning disc would only be visible on camera, not in person, and only when speed and framerate are perfectly synchronized - a little bit off, and they would be drifting clockwise or counter-clockwise, a lot off, and it wouldn't be recognizable.
