the pen tool is the only one i know how to use from your list. but what the pen tool does is be able to change the size or color of something. in my photoshop class we had to change the color and lower the car. idk if you have the email option but i could email you the way to do that with the car, then youll know how the pen tool works and apply it to other things.
