How would a hollow, layered lattice planet work?

I had the idea to make an artificially constructed planet which is terrestrial, but has the diameter of Jupiter. Instead of being a solid sphere, it would be five spherical layers, with land on the outside and inside, connected with pillars and with holes to let sunlight through to deeper spheres.

My current design is to have each sphere resemble a complex polyhedron (I don't know which ones yet.), with the edges being spars of land that curve and the sides being the holes, and connected to the sphere above and below with pillars. Each spar and pillar would have crust, mantle and core layers, with the core made of unobtainium that was enchanted so that its structure would be stable no matter what (which means ignoring hydrostatic equilibrium). It would also alter gravity so that 'down' is in the direction of the nearest land, and project a magnetic field (though I'm not sure if that particular aspect needs to be handwaved like the others).

What I'm curious about is, assuming there's enough magic handwaving to make it possible for humans to live on most of the planet, what other factors would make life different there?
