  • To all three only true answer is: it depends on what modules you installed, how you configured them, and what exactly you mean by "admin". Nothing more, nothing less. Voting to close as too broad for now.

Using Drupal core, two users editing the same node concurrently would cause a conflict; the second user would get an error ("This content has been modified by another user, changes cannot be saved."). This would only happen on node_save(), once they have submitted the form. A more user friendly option would be to use a module like the Content lock module which highlights an active edit of a node and locks it for others.

Any number of editors are supported on a site simultaneously; the only limitation is editing the same node (and server resources).
