Hoping for some help to find clarity in this sea of text

This 1818 prosessetti starts on image 59 of 388 https://www.antenati.san.beniculturali. ... 40/wEA89xq
For some reason, what I think is about the birth/baptism of Agostino Andreola on 17 January 1799 to Simone & Angiola (Angela) Maria Giordano seems to run very long. Some things that pop out at me on image 59 are patterns of names like 'Carmina Colavita ,56, fu Giuseppe, moglie di Matteo Margoliccio (future Margollicci)' then on image 60 'Carmina Colavita=Domenico Gianni=?=Maria Matrangola, di Giovanni, 52, moglie di Flavio Andreola' etc....(Image 61 is repeat of 60) that runs to left side of image 64
?s on this part are: did I get the basic info for Agostino correct? and What/who do those names mean---witnesses? godparents?...?
On right side on image 64 and right side of image 65 appears to be the 9 January 1799 birth of Antonia Fratta to Giuseppe & Maria Magaldi.....correct?
On the right side of image 66 appears to be the death of Angela Maria Giordano...unsure of this date in 1806...is it 22 Sept or Oct or 9 Sept or Oct?
And finally on image 73...can I assign any relevance or connections to the Giovanni Andreola 37 & Leonardo Andreola 39 who signed testimony?
Thanks for any insights!
