    Pax!
    I found a very special Credo III (V) with three flat signs. I think it's found in http://chabanelpsalms.org/introductory_material/Public_Domain_Chant_ACC/LapierreKyriale.pdf
    I always though Gregorian chant could only use one flat sign (Bb). Please explain this? And when people chant Credo III at Mass do different choirs/scholas use different sheet music?

    Four-line Gregorian notation doesn't (tend to) use key-signatures because the notes are relative to each other, not to a fixed pitch in the audible spectrum.

    The linked PDF is a modern-notation transcription, which would need a key-signature of some kind (even if it is no sharps and no flats) to indicate on what specific pitch the notes of the melody are referring to.

    (This is not the same as, but vaguely analogous to, why instrumental parts of an orchestral score have different key signatures.)

    Gregorian notation does not have more than ti flat.
    Do ≠ C (modern C that is)

    Yes, of course. Just like different productions of Hamlet will use different editions of the script. (Or, more to the point, like how every hymnal has it's own representation of Amazing Grace.)

    Credo III is a Platonic ideal form. Any particular printed edition is merely a shadow of a representation.

    notation ≠ music
