I now did find a Mascalzonelatino (Atos Dell'Antico Cerberus x Baghera) who is HD A and Giovane Promessa ENCI. Not sure if this is the correct Mascalzonelatino, since there are more than 10 in ENCI database (all breeds). But this happens to be a Cane Corso, HD A and Giovane Promessa ENCI (promissing youth also refered to as Young Italian Champion). But this is not a Championtitle which is accepted for Championclass. But I think this might be the Mascalzonelatino you have in your pedigree.
As for Noe and Nefertari. Both have no official hipscore in ENCI database. Noe has been in Holland and also there no official hipscore. Noe is Dutch Champion. Nefertari has no titles in ENCI database.
Italian Championtitles are easy to check on the SACC website
http://www.canecorsoitaliano.it/campioni.html or on the ENCI website. If you have LIR number, it is also easy to find them in ENCI pedigree database, where all titles and hipscores are mentioned.
