Paint repair - small lined dent...

Nothing big, maybe a chip or two and a small line with a less than 2-5mm indention.

Anything that can be done for this?

would need to use a hammer and dolly for that line. definitely needs to get pro help to bring it back to factory spec. but im not a body guy, you can probably try to get a hammer on the other side of the dent if you can and tap it to flatten it out, make sure to have a thick piece of metal on the other side. but wait for confirmation from knowledgeable members if that would be the thing to do.
