Fighting and sleeping are located in actions. Meaning character actually should DO them, ie fight with someone or actually sleep.
Battle and rest are general tags. For example, character could stand with a weapon in hand without fighting someone, and it may count as battle.
Or she could drink coffee sitting on a sofa, or reading a book under a tree, and it counts as rest.
Naturally, the same picture could be suitable for profile and battle, or for profile and rest. That's why you can freely use tags in the tagger.
I can tag an image SFW and Striptease, will it still work as intended or does it need to be Nude and Striptease?
If she's really SFW, without nudity, then yes. Otherwise we may show her SFW picture when we need a nude one.
Whats Healing? Themselves or others?
Others. Like casting non offensive spell, being dressed as a SFW nurse, have any kind of medical equipment in hands, etc.
Girlsmeets tag is only for meeting girls you dont own or employ?
It's used in interactions with hired ones too.
Basically, it's a picture when character stands straight, not under unusual angle or something, and looks in the camera. Ie when you talk with her.
Mostly with monotonous backgrounds, but not necessarily too. You can take a look as GM pictures in my packs, the tagger allows to quickly find pictures with needed tags via mask option.
Of course the same picture may be suitable for both profile and GMs.
