terminology - Question about physical principles



How are principles created i.e. how is it decided that something qualifies as principle?


What is the difference between a principle, a law and a theory?


Were there any principles that were proved to be wrong or are principles always right? For example, the reason why Einstein proposed that the speed of light is constant is because the Principle of Relativity would be violated otherwise.


Are physical principles comparable to mathematical axioms?


Is there a list of physical principles? I couldn't find any on google.
