if they dont have a crease and arent in body like sometime you can pop them out and its harder to do on smaller dents. but if there is any kind of a crease or fold they wont just pop out. The problem with just poping them out is that when a dent occurs the metal gets stretched, so there will still be a faint ring where the dent was, and the area will be easier to dent again. even just leaning against it could cause the dent to reappear. to fix it properly the dent needs to be pulled out and locked into place. there are several ways of doing this, my favorite one involves a torch, but you can also lock it back in with just hammers in dollies. the thing is that every dent is unique and requires a slightly different technique.
but to properly fix the dent you have pull it and reshrink the metal which mean you'll have to primer and repaint that area.
however some of your dents might be able to be popped out and look acceptable for a driver. the bottom of your fender and your door won't just pop out, but some of the smaller ones might. (just looked again and looks like all your major dents are either creased or on a body line, so its gonna take some more work)
for body work pull the dent to within 1/8inch of where its suppose to be, lock it in, bondo, sand, reapply bondo, sand (repeat until correct form and not more than 1/8inch of bond) primer, sand, primer, sand (until 100% smooth), make sure to sand out all scrathes with atleast 400grit but 600grit is better, then sealer, paint, paint, paint, (until covered), clear, clear, clear, bake/cure. buff if needed
