Hi,
most of the time it will end up being the door lock modules, seems you have gotten some life out of yours, you can pull one door panel just to make sure but ive done hundreds and almost 100 percent of the time it is the modules, and yes all four can go up at once, they drivers door is the only one that gets more use than the others, anyway check it out and replace the modules as needed, I would also recommend dealer parts
thanks
