The men you name are commonly referred to as antediluvian patriarchs, though Abel is not a patriarch, since Abraham was in Seth, not Abel. Antediluvian means "before (the) flood".

Abraham is a "father of the Hebrew people" and Isaac and Jacob are more specifically so. It was Abraham who was the second party in the "Abrahamic covenant" when God committed to him to bless the entire world through "his seed". Adam, Enoch and Noah were indeed patriarchs and fathers of all mankind but Abraham was the father of "God's people" (Ps.13:1, Is.40:1) from whose perspective we have received the scripture.
