The dent on lower panel will be pulled out by drilling small hole (unless a pro denter uses a vacuum pulling technique), then it will be painted after filling that hole with putty.
Scratches on door might be removed by scratch remover or brushing. If not then it will be painted. Get it done from 3S. They will use genuine paint according to the color code of car. You won't find the difference if they do it properly.
Otherwise, leave it as it is. I got more deep dents on Cultus panel than this. Plus panels are now already rusting thanks to build quality of Suzuki Cultus.
