Pennies turn color naturally over time from orange to red to brown. The time varies with each penny. Your pennies seem to be in various stages.

The green color is from adverse environment. It is called electrolosis, a chemical reaction on copper. It is often called corrosion.

What about the first picture? Someone altered it? And thank you for the info on the others.. I was thinking it might have been from oil on peoples hands, just like oil and water in the parking lot it causes a rainbow color..

First one looks like nail polish or paint to me. Is there a film? or is it just the copper is a different color?

As they change color, sometimes different areas of the coins change at different rates.

No film or scratch marks that I can see.. which is odd.. its to good to be painted. The Lincoln on the inside is red, but nicely visible

I have seen pennies the same shade of red your picture shows. If it is topical, you can remove it, or scratch part of it off. It really doesn't matter, it is a normal coin. I hope I answered your questions about colors.

The first coin is coated with something, that is not patina. The 1975 appears to be completely normal. The next three Zincolns are too blurry to clearly see what is going on. The last coin also appears to have some surface contamination issues.
