Well - I guess what hyperintrovert has meant is that these cards are already included in the BetterRepack, you don´t need to download (excepting you want more of them from other creators).
You find these cards in UserData/chara/female/Modpack or xxxxxxxxModpack (NextGenSkin).
In charamaker you can load them if you open the Modpack folder

As you can see in my screenshot you can create your own subfolders in chara/female to manage your cards.
But pls note that to play with a card from a subfolder it should be copied into chara/female and assigned into a group from there, otherwise this character won´t gain status points.
If you have downloaded character cards from otherwhere the cards are dropped into UserData/chara/female (or xxxx/male, if it´s a boy).
If downloading a character card you should watch if this card needs special mods and download them too.
Extra mods (if .zipmod files) going into mods/MyMods.
For example this Jill Valentine above needs a headmod from Cunihinx (included already in BetterRepack - mods/Sideloader Modpack - Exclusive HS2/cunihinx).
Btw before we proceed to help you into this game let me remind you that´s usual here to give "Likes" to helpful answers
