It seems like this might be about animation ultimately, rotoscoping possibly.
If so Photoshop may simply not be a great fit for the task and Animate, After Effects, maybe even Illustrator, … might be worth checking out for the task.
Convert your layer to smart object and copy it several times.Each copy of the Smart Object will contain any changes you make while editing any of these layers.
So you want same drawing against different backgrounds, right? There are multiple options to get things done and again instruction will depend on what is your end goal.
If you want different background beneath each drawing then how drawing on multiple layers at once differ from duplicating drawing to multiple layers?
Hi this is not possible as told Miss @barbara_a7746676 actually this because, so we can control everything if you want to send this client at the end you can merge layers it will become one...regards

As long as the layer with the paint brush in on top of the other layers and as long as the area outside the painted area is transparent, it will appear to apply to all layers even though it is only on one layer.
If you absolutely need the paint on each layer, you can duplicate the paint layer as many times as necessary, and combine the paint layer with each of the other layers individually.
I don't know of any way to actually paint on multiple layers at the same time.
