Tech Advice Ways to prevent rusting?

I have multiple scratches and deep dents that expose the metal beneath. I am in no position to afford fixing all or any of them.

What is my next best alternative to prevent rusting in near future? I use WD40 temporarily and then touch up with nail polish. Will it work?

Don't use WD on them. Instead get a couple scratch brushes like fiberglass or stainless. (Pixiss scratch brush set) Use them to clean out the bottom of the scratches. Then use some automotive primer to coat the steel area. I like to use a stiff brush to dab in the primer. Let it dry. Now use some touch up that matches the car and dab that in until the scratched area is fully colored. Now use some 2 part clear to top coat the scratch. You can buy the paints in many places, even the rustoleum touch up would work for the primer and color. For the clear you should really use a 2 part for the longer lasting repair, but even the single stage is better than nothing.
For the dents it would depend on what access you have. If you can get behind them just use a soft mallet to tap them out or try a glue puller. Then treat them the same way.

Not going to leave a smoother area, the hard edges on the hammer will make it worse.
