Rear bumper minor dent how to fix it?

If its a "smooth" dent in a plastic bumper , you can heat it up with a "hair-dryer" and it will pop pop out and resume its original shape on cooling .

Yours unfortunately requires paint ....

I would first use some polishing compound and buff-out some of the scratches, then put a good coat of wax on it to see what it looks like.

if the scratch goes into the SILVER paint it really needs to see a bodyshop. An abrasion to the CLEARCOAT ONLY can be gently wetsanded with 600 grit and then polished. There isn't much depth to the paint so it must be done cautiously. Personally I think your car's worth a pro's attention- if you get a quote, get more of them and don't choose the lowest one!

A top notch auto body shop would be my recommendation.
