Let's do a brief synthesis of the parallels and contrasts first, taking the most important points from each:

Kobeni (least amount of connections)
>both clumsy spergy women forced into a date with Chainsaw Man by a Devil
>one tries to kill Denji when blackmailed with starvation by Eternity Devil, the other in the same situation is willing to starve to death rather than kill him, and then saves him

Himeno
>both kiss him forcefully on chapter 21 of their part
>contrast: professionally and sexually, Himeno is more experienced than Denji. The opposite happens with Denji/Asa
>both are once again blackmailed by the Eternity Devil. Same response as Kobeni
>a sexual encounter between them is prevented by Control devil

Reze
>both are the only two real romantic prospect for Denji outside Makima (Asa, Makima and Reze are the only three girls he ever went on a date with)
>One approaches Denji because he is chainsaw man, the other because she thinks he is not Chainsaw Mna
>Both "fall in love" due to the same exact romantic gesture by Denji
>One is still willing to manipulate him and hurt him and kill him, out of personal gain and feeling rejected, the other risks her life even after feeling rejected, just to save him.

Power
Endless list of intentional and canon parallels.
>love for cats
>cat + woman being saved from Bat Devil
>both manipulate him with sex in order to save a cat, which would otherwise be killed by a Devil
>contrast in their attitude when it comes to actually kill Denji
>only two women who were willing to die for Denji (Power manages to overcome even Makima's control for Denji)
>lesson in the importance of mutual respect and deep care in a relationship, beyond sex
Makima
>one loves CSM and despises and hurts Denji
>the other loves Denji, want to protect him and her main goal aside that is to kill CSM
