Like Miztah Raza said, you have to use BrienJs PAC Archiver, you open the specified ed??.pac within the edit folder to find the texture, you have to have a Jtag rip of the game though. For the ed02.pac and the ed04.pac, the pachs alternate male to female, for example P000.pach is face texture 1 for male, P0001.pach is face texture 1 for female, P003 is face texture 2 for male, and so on. The textures within the pach are the first .BPE for face textures and the first 4 .BPE for body, export them as .tga for them to open in photoshop.
Here is a list I've made of what's in a couple of the folders within the Jtag rip.
ch folder
edit folder (pacs that say nothing doesn't necessarily mean nothing, I just didn't find anything within a couple of pacs so I moved on to another pac.)
