Will these only work on metal pipes?

Yes I would have thought so. The magnetic field generated passes through the pipe whatever material it is. They definitely work.

Are these Bar magnets

They're really powerful rectangular magnets set into the yellow case each side of the pipe. I'm assuming here but I guess they're Neodymium.

Are they any good for preventing a limescale build up in a shower?

Our area suffers from very hard water. I am a convert to magnet theory but it is one of those things it is very difficult to actually prove. I use one pair on the water inlet from the mains and the other on the spur connection to the shower unit. I am certain they work. The best indicator I have found is that my electric kettle gets no where as furred up as it used to. Hope this helps.

can I use all 4 magnetic limescale removers together on my main inlet pipe

Yes you can, but you shouldn't need to. I put 2 on my main inlet pipe and 2 on the pipe going into the hot water tank. I have very hard water, but doing this has just about eliminated all limescale issues
