I may be totally wrong here but I don't think you can determine the NPK with the information you have provided. Each of the 6 items you listed have a wide range of variables depending on the amount of chemicals and their concentration. With 6 variables (and no info on quantities) it would be impossible to even guess at any values. Sorry.

Easiest way to be sure, is take a uniform sample to a lab and $8 later, you will know.

Curious, what are rusty nails bringing to the party? All wood products will tie up your nitrogen as the microbes that are going to digest it will need all available nitrogen they can get to do it. So your effectual nitrogen will be 0.

Only a soil analysis will tell you. If things are growing well, who cares?

Lots of folks include iron in their homebrew fertilizer mix. The plants are supposed to benefit from the iron deposits in the soil. DW always asks for all of my rusty, bent, or otherwise trash nails. I keep a 5 gal. bucket handy for throw-aways.

Like others said, it's almost impossible to tell with the available information. A lab test will be required. However, NPK ratio isn't normally the best part of compost, it's the many trace mineral and secondary nutrients available, as well as te microbial life which is great for your soil.

I'll add:

. . . And, the the ability of organic matter to loosen the soil, allowing easy root development while providing more consistent soil moisture levels.

Good stuff, quality compost is ;).
