Within each Folder, yes. Globally, no.

Not in the sense I think you mean. On the other hand, any object may be
called by name at any point in the hierarchy at or below where it is
defined *if* it is the only object with that name in the hierarchy.
This object can also be selectively overridden by placing a same-named
object at any point in the hierarchy where you want a different result

Not in the way I think you mean. A better way to put it is that Zope
determines whether there is a publishable object/method that can be
reached from the location a user specifies in their request.

If you moved them up, probably... if you moved them sideways or down,
In order to get anywhere with Zope, it is *essential* to understand a
key concept called Acquisition. An excellent intro to Acquisition is
Rule of thumb: put heavily-used objects at the *highest* point in the
hierarchy over which they apply and use folders primarily to enforce
differing levels of privilege/access.
