Yes they can, for instance, two radio buttons can (should) have the same NAME but
they must (should) have a unique ID.

The NAME is only used when a FORM and its child controls are sent back to the
server. The server identifies each control thru its NAME. If the server is not
interested in the value(s) of the controls with the same name, then it does not
matter.
JavaScript on the client-side though typically uses the ID (which should be
unique), but if an ID is not specified, then it will use the NAME.
