Cattle don't really need other cattle, but they are happiest when with others of their kind since they are herd-oriented animals. They feel safest among others since they are prey animals, and for prey animals, the greatest defense against predators is staying in a group or herd.
None. Cows may need grazing area but an area does not need cows!

Cows don't need money
Cannibalistic. But in reality, cows don't eat other cows (they're strictly herbivores) so this question doesn't apply to them.

Everyone needs exercise - but cows just don't bother.
