It's not all translated since I haven't started on it yet (it's a different script that RPG Maker Trans can't extract into the script folder so I have to manually translate it with the game editor).
From the center row after the description:
性関心:消極的 (Her interest in sex: Either passive, interested or aggressive)
好感度: 33 is her affection (intimacy).
淫乱度: 0 is her lewd degree
性交回数: 0 is the number of times she had sex
中出し回数: 0 is the number of creampies she's had
経験人数: 0 is the number of men she's been with
初めての相手: Not is her first partner (Either MC or Rodrigo)
出産人数: 0 Number of births
妊娠中の子供の父親: --- is who's currently the father of the child she's pregnant with.
Accompanying is who she's with when she's not with MC.
For Rodrigo's first night, when MC becomes lovers with FMC, there's an option to talk about his netorase fetish with her. Keep choosing the NTR option will deviate the vanilla defloration path to NTR. When she agrees, go next door in the inn and have her sleep with Rodrigo.
For the event with the alchemy shop girl, the first scene is a story event when MC and FMC agree to help Sana's request (can be obtained from adventurer's guild, I forgot which one, but finish one of the crystal's guardian bosses).
The second event for Sana is doing swapping play with her and her husband, Kai. I don't remember how I got it when I last played it a year ago, but I remember you have to trigger it by getting the ruin door open and then discussing how to weaken the guardian by swapping partners with the couple. (I think you have to be defeated by the guardian boss in the blue crystal and then prompt a quest to weakening it, check the memo if you receive it).
The two blonde hair events are also story events that you get if FMC agrees to give her body as a reward for the adventurers for defending the town (non-vanilla route so she gotta be interest or aggressive sexually, aka high lewd and experiences).
