TL;DR
What are the "central/axiomatic equations of physics" from which all others can be derived?
What are the "central/axiomatic equations of physics" from which all others can be derived? For example, it couldn't just be Newton's 3 laws, because they don't say anything about electric charge, besides the fact that there is relativity. Is there a minimum set of maybe 8 equations and/or principals from which everything else in all areas of physics can be derived?

Physics isn't a formal axiomatic system.
 
I think the most fundamental principle is least action, minimality. Nature doesn't waste energy on detours - evolution aside, which is due to the lack of a mechanism for optimization.
