ideally you place them where they are when projected into 2D, you might even 
draw areas for them ;-)
Maybe you could do it going level by level in josm, filtering out the other 
levels while editing (tag "level"), but honestly OSM isn't prepared well for 
complex situations, e.g. buildings with differing floor heights, split level 
and/or varying relative vertical positions  (e.g. created by ramps). You would 
need a true 3D model in some cases (and specific editor support), and surely 
the min_level definition of the simple 3D concept  will be demonstrated as not 
working in these circumstances. It is a "simple" concept, fine for many 
situations but too simple for complex cases.

addr:floor is about the address, "level" is used more often.
