How do I whit mi project game

hello friends I have a question about my game

How can I make card 1 move to the place of card 2 and it is to the place of card 1... that is, that it moves to the place of the previous card and not on top of it and the same for the cards 3 and 4

I attach an image as an example

I think I would do something like this, when dropped, we compare the new x position of the object
