As already noted the brake rotors on all cars will have surface rust on them. Its raw exposed metal that is being heated and cooled. The face surface is continuously being cleaned by the friction of the brake pads on the surface but the edges will attract light surface rust. It's little more than cosmetic.
The inner drive shaft CV again is nothing more than cosmetic. That said you wouldn't see that surface rust on say a late 80's or 90's Honda even after 30 years. They went the extra mile and components had surface treatments, anodizing, painting or the like to keep things looking fresh.
The brackets around the welds that the paint hasn't adhered properly and it looks like paint as fallen off or stone chips have exposed raw metal. Again not ideal but hey that's how they do things now days. A light dusting of paint. Perhaps not even any primer. That said over the life of the car it will be nothing more than cosmetic.
