If the multiverse exists as the scientists claim then do they revolve around each other?
I'm not sure any scientist CLAIMS that a multiplicity of universes exists. It is a speculation (unsubstantiated fantasy), that some engage in.
Very few professional cosmologists spend much thought on it. It just doesn't work into regular day to day research. So it doesn't come up much in research articles published by the astronomy/cosmology people.
But some string theorists like the idea, and people who construct imaginative inflation scenarios. Some of them write about it.
So I can try to answer your question based on not on CLAIMS (which need some evidence) but on the fantasies or speculations of a few people mostly outside observational cosmology.
In fact, in all the speculations I've seen, different pieces of the imagined multiverse are NOT imagined as
orbiting each other.
However Steinhardt (also inflation scenario inventor) has a picture of a 4 or 5 dimensional universe in which 3D branes BUMP against each other every trillion years or so. But he doesn't call the separate 3D branes "universes". The 3D sheets are part of the same universe because they can interact, that is bounce against each other. We are imagined to live on one of these.
Again this is pretty exotic and not something that a working cosmologist would normally be considering.
If you fancy the idea, however, you could read Steinhardt's new popular book about it called Endless Universe. Look it up on Amazon.
