The right way to mate

How can I make the seal part go with the piston until the stopper (due to pressure in the cylinder)?
Right now if I pull the piston it does not pull the seal with it.
What is the right mate to achieve this?

I'd probably make a sub-asm of the two seals and the piston. (how are the seals attached to the piston? If some mechanical fastener, then a fixed mate between them should be fine).
Then put a cylindrical mate between the piston center (of that new sub-asm )and the cylinder center. You could add a mate connector in the part studio at that location to make that easier. To make it stop the right distance, inside the cylindrical mate will be a z limit. That's how far the piston can slide in each direction.
Here is an example. I went with a simpler group instead of a sub-asm as I wrote earlier.
