> Could you explain me the correct way for calling them and is the definition of the external functions done with copying the given snippet into "Libraries/External function declarations" in the same form how it is at the moment?

It sounds as if you need to spend some time studying C.
Learn what the extern definition does, and how to call external libraries from C-code.

In your case the S-Function acts as a wrapper for converting the C syntax that Simulink expects/uses to that expected/used by your library.
That conversion is done in C and you need to have a good understanding of how to do it before writing the wrapper S-Function.
