Starting from the array of the above normalized coefficients what are
the
steps to perform the transformation of the coefficient in order to
filter,
- Find the transforms in a textbook.
- Analytically derive the transformed biquads.
- Implement the derived formulas in a programming
language of your choise.
- Apply the functions to your prototype filter.
- Use the resulting coefficients when filtering
your data.

Or buy a filter program that does everything for you. I ise QEDesign from

Momentum Data Systems (www.mds.com)

I posted precise questions (C code, code examples, ecc) and I obtained
generic answers or suggestion to buy a library. Is this the spirit of the
forum ? Thanks anyway for the help.

You asked for finished code. You were given references to the relevant algorithms. If you need help understanding the C (or any other) language well enough to express an algorithm in it, you should find another forum. This one is not about C, it is about processing signals.
