It depends on the mare. You may feel milk in the mare's udder when she has a month left to foal, or you may feel milk in the mare's udder right after she has foaled.
The best sign of birth is the 'waxing up' of the horse's teats. Dried milk will be seen at the ends of the teats. Birth is usually hours away.
All mammals have teats, as they are how the offspring are fed milk.
Yes, a mare is a typical mammal giving milk from it's teats to it's offspring, the foal.

Two.
Depending what animal you are referring to, the other teats should do.
Teats are the equivalent of a human's breasts, babies drink milk from them.
The teats on the udder.
The udder should feel firm, with a slight give to it, and have easily expressable milk from both teats. If the foal has recently nursed, the udder may feel softer.

The udder, just like in a cow. The udder is stationed in the same area as a cow's, only there are just two teats, not four, on that udder.
yes this does mean she is pregnant after awhile the milk will come out if you squeeze the teats
