A cow should have four functional teats as maximum. She can, however, have two or more extra non-functional teats, none of which affect production nor milking ability. In dairy operations, though, these extra teats need to be removed so that the person with the milking machine doesn't hook up the vacuum pump to the wrong teat.
No. It's normal for a cow to have a couple extra non-functioning teats.
No. A cow only has four teats, not 16 or 8 or 7 or whatever number you come up with.
So they can nurse their babies and so they can be milked. that's how we get our milk in the store. so those are very important on a cow :)

For Sanitation purposes prior to milking the cow.
The udder must be tucked up neatly between the hind legs and the teats should be small. Each quarter of the udder should be equally spaced, and the udder itself has a level udder floor. Often this is hard to see if the cow has a calf and the calf has only suckled on one or two quarters and not all four. But typically a cow should not have an udder that hangs down past her hocks, have large teats, nor have the teats spaced too close together. Check out the related links below on udder conformation of cattle.
As many as 50% of the dairy calves are born with more than two teats on a side, but these extra teats, called supernumerary teats, always form on the same line with the two primary teats on each side. If the supernumerary teats are allowed to develop further then they can hinder the milking process when the cow is mature. Even though they usually are not very productive in making milk, they can add to the cow's risk of the udder becoming infected with bacteria. With those risks in mind, the extra teats usually are removed when the calf is only a few days old
