So many questions!

What are the Degree Contents of each part?

Look at the syllabus from whichever universities you are thinking of studying at.  There are so many courses, including ones that overlap between subjects.  Don't assume that Science is a subject in itself.  Most universities will teach specific sciences (Physics, Biology, Biochemistry, etc.).

would the Degree in Science or Technology or Engineering or Mathematics be considered at par or equal?

That all depends who you're asking, and what you want to do with the degree.  And what you mean by "equal"?  If you want to design a new suspension bridge, you might employ an engineer, but not a biologist.

what would the job responsibilities of each Degree Graduate like Science Degree Graduate, Technology Degree Graduate, Engineering Degree Graduate and Mathematics Degree Graduate?

I don't think that's answerable.  The jobs that people do may only vaguely relate to the degree thay took.  Many years ago, I did Electronic Physics as a degree.  Now I write software, and documents.  Lots of documents.

In some cases, the responsibility of a new graduate is to flip burgers at a fast food outlet, because they haven't found a better job yet.

How would a professional institute or society or council will treat each kind of Graduate under STEM?

It depends which society you're trying to apply to.  Here in the UK, there are lots of institutions, that specialise in different subjects.  So you'd join the one that relates to your specialism.

The IET is a bit of an oddity in that respect.  It used to be the Institution of Electrical Engineers.  But then it decided to rebrand itself as the Institution of Engineering and Technology, in an attempt to take over the market in engineering institutions.  It managed to swallow up a few smaller institutions.  But a merger with the IMechE failed, and their attempt at taking over the engineering world fizzled out after that.
