Unless you are looking at the scene from 5 different angles or positions, I don't think you need 5 views. To simplify things you could also look into using a basic setup: one scene and one view. Have 5 objectContainer3D, one for each floor and go from there. If you need to use things like alpha or blending effects use ownCanvas or layer (in Lite) to tell Away3D that these need to be in their own sprite.
