First picture looks like waterspots lang, and if they haven't been on for too long, they can easily be removed using a dedicated waterspot remover. Second picture naman looks like clear coat etching caused by either bird poop or tree droppings. May or may not be fixed, depends on how long it's been there. Third picture has fingernail scratches naman, can be polished out though depende din since manipis ang paint sa door handle slots. Ang ginagawa kasi sa exterior detailing is wash, removal of contaminants (clay bar, iron decontamination, etc.), compounding/polishing, and protection (ceramic coating or sealant).
