If you are asking can one wall switch control two or more lights, then the answer is yes.

If that is not your question, then I do not understand what you are asking.

Or I think you mean you have a switch and want to know if you can tap the black at the swicth to give power to another switch, to which I would say sure. Run you hot black to the switch, pigtail to the swuitch and continue that run to the new switch.
