How long will the bottle last for short cropped hair?

If you can draw out a reasonably accurate measure (e.g. I use an old syringe with no needle) you should easily get three goes and perhaps four. It shows on the bottle how much is inside divide by 4 see how you get on.

Once you open it and use some do you have to throw the rest away or can you save it for next times use?

I use it for facial hair. In a plastic mixing container (e.g., a store bought salsa, hummus pot, etc..,) I mix 2 even parts of about a 5p size each. One box will last me about 1 year.

If I dont mix whole quantity once, can I use remaining later ?

I wouldn’t recommend it, because you have no idea whether it would be effective as when you first mix it and might end up with a less desirable result

Can this dye be used on pubic hair

No it's harsh for normal skin use. You don't wanna be itching down there! For the head only for sure.
