Hello Agnieszka Kasprzyk,
you were asking:

The ways you have outlined are "canonically equivalent", so your
software should treat all of them as equivalent.

Multiple diacritics are placed outward from the base character,
so you have to enter
- either the base letter, the diacritic which is closer, the diacritic
which is farther from the base letter, in that order,
- or the base letter with the closer diacritic as one character,
then the farther diacritic as the combining character.
