There are a few ways to resolve this dent issue as the others have indicated.
Another Possible Method
glue these plastic ding tabs to the dents. You can find them by googling "plastic ding tab"
You will use a hot glue gun and hot glue them to your various dents.
Use a dent puller slide hammer. The tip should screw into the plastic ding pullers.
Pull the weight of the slide hammer to where the ding tabs are attached to the dent and give it a good pull. When the sliding weight hits the stop at the end of the hammer the transferred energy will pull onto the glued tab and pull the dent out.
You may need to repeat the operation a few times to get the result you are looking for.
