The most common exercises to become taller are stretching exercises. If you want to make good progress, you should stretch your legs, torso, and pretty much your whole body every day. However, there are more exercises than just stretching that are useful for our purposes such as swimming, sprinting, and biking. Make sure you have a healthy diet that provides your body with all kinds of nutrients. Your body will need it to stay healthy while going through the process. If you can get taller naturally, then limb lengthening surgery can be considered as a permanent option as well.
