if by recursively you mean dynamically, then you are looking at the 
Decorator design pattern:

if you mean some shared resource between all objects of a particular 
class, you should look at static member variables aka class variable.

You can override methods of your base class in the inherited class, but not
variables, I think, unless they have 'set' functions.
This does not affect the base class though.

This is language specific.

A common lisp object (or any other object in a CLOS based object system) for example has the power in practice to change not only its class, but also the rules defining the object system itself (and therefore the behaviors of all classes). If your question isn't "can" but instead "should", the standard answer is probably no. Unless you ask many ruby programmers (if I am not mistaken, they do it quite a bit and have a name for it: "monkey patching").
