Only by waiting until she kids.

If you are talking in terms of crossing different breeds of goats, then you can cross any two breeds of goat. The cross of an Angora goat and a Pygmy is called a Pygora. Crossing a Nubian and a Pygmy will result in a Kinder goat. Also, there are many crosses that don't have specific names. For example, I have Nubian/Boer goat crosses.
A goat can have up to 1-4 kids, but the most common is 2
No, goats have two nipples but can have up to four and even five kids.
A boer goat can have anywhere from 1 to 5 kids. Multiples (2-3) are common.
Between one and five kids.
Non. "babies" are produced by humans, Goats produce "kids". A goat has two teats and therefore the maximum number of kids is normally two.
2 kids
It depends on how many kids she has - it is normally one for each kid.
Depending on how many eggs are released from the ova at the time of copulation determines how many kids are born - so it is the female goat.
Generally around 5 months, but make sure the goat is in heat first, or it might be longer.
Goats can have up to three babies. We have a goat named Merry and she was pregnant. And she was FAT i mean FAT!!! we thought she would have three babies. But she ended up having one big one! So... if you have a fat pregnant goat. You might be fooled cause she could end up having only one!
