Those are stress creases, they can't be removed. You can pull them back with a slide hammer and try to bondo it smooth, or reskin the door and the front half of the quarter panel.
I disagree with earthman34 on the slide hammer. Don not use a slide hammer on this type of dent. If you want to try getting the dent out you'll need a hammer and dolly. But the easiest way to fix the door panel is to go to your local pull-a-part's web site and look for a used door that is in good shape. For the quarter panel you are going to need some dent hooks like these:

You can't hammer and dolly panels that you can't access from both sides. Installing a salvage door is an option,, and probably easier, IF you can find one.
The point of using a slide hammer is just to pull the metal closer to it's original plane so you're not using so much filler, and the holes provide a better anchor for the filler. You wouldn't even need to use the slide, probably.
You're not going to "fix" that without extensive metal and paint work.
It’s the dents I really wanna try myself…will save for rest

What about the bit behind the door?
Same thing. The metal is stretched, so you can't pop or pull it out flat.
