replace patches,flags,add text/change text

I have got a .pak file (pakchunk99-Mods-MW2019_Raider_maskedAll_MC_P.pak) for ready or not with some models there and textures. I ask you to change/replace specify flags to other ones and also change patches (both arms) for other ones (all attached files will be named where to place it). When there is some text like "g-25" - change it to ALFA like on attached screenshot (same font).
The other thing is .PAKing this mentioned above with the rest .PAK files (attached screenshot with list of items to be .PAKed in one file).
