Good rule of thumb, you want a nice even gap around the door. From the pictures it looks like your gap is bigger on the hinge side at the top, hence the door is hitting the jamb at the top when closed. You can use bigger screws and pull the top tighter, or shim out the bottom. If you shim out the bottom too much you might now find that you are hitting along the entire jamb when closed, I would personally try pulling in the top hinge. Several things to try:

Make sure all of your hinge screws are getting a good bite and tight on the top hinge.

Remove the top hinge and make sure that the leaves lay flat when closed. If they are bent you can either replace the hinge or just bang them flat with a hammer.

Remove one of the top hinge screws and run a longer screw into its place on the jamb side. Best to use something long enough to hit the stud and get some penetration, and using a power driver will help you get it pulled in. The middle screw is normally towards the center of the jamb, which will help insure that you hit a stud vs sheetrock. If you do this right you should see the jamb move towards the wall, which will pull the opposite top edge of the door away from the jamb.
