1)I think what looks like & is bleedthrough from another page. If I were attempting to extract this image I would think the surname is Graziano. Each baptism is one child, even if it's a twin. In the case of twins there may be a notation "gem" indicating this but the twin would have it's own record.
2) heri means yesterday, the day before the sacrament was administered.
3)I may be misreading the document: the parents on the baptism (image 2) are Cesare Gaglio & Providenza Lo Ra. the parents on image 3 are Francesco Galgio and Rosaria Vitale.
info from my research: I have a Cesare Gaglio married Providenza Lo Re in Terrasini on 6/12/1823. This Cesare is the son of Giuseppe Gaglio & Antonia Saputo.
