Yes, actually they do. A heifer can be weaned and separated from her dam for several months, and when they are united back together, they do and will recognize each other by sight, smell and sound. A cow herd can often form family groups within the main herd, and in these family groups are half-siblings, aunts, grandmothers, sisters, and mothers.
There are many differences between humans and cows. Cows are quadrupeds and humans are bipedal. Cows have stomachs that are separated into four compartments, while human stomachs do not have separated compartments.
Yes, cows have best friends and they become very stressed if they are separated from them.

Cows and other herd animals play only when they are young - they usually mature and stop playing after their first year. Playing helps babies learn how to use their bodies and run fast, get along with other animals in the herd, and to decide who is the boss animal and who is the underling.
They aren't. Bulls are when they're quite young, but not cows.
First of all, there is no such thing as a "male cow." Secondly, it is the cow that is primarily responsible for the care of her young, not the bull. Bulls rarely ever "get the chance" to care for any of their calves, because most of the time they are either set on breeding his girls or is separated in another pasture by himself or with other bulls and steers. The rare chances that a bull does get to care for his calves is if the producer likes to have his bull in with the cows 24/7/365 in a year-round breeding operation.
Birds are not categorized as mammals because they lay their young on the outside of their bodies by egg and feed them worms and other insects by mouth. Cows are mammals because they carry their young inside until ready and they feed them by nursing them with milk from their bodies.

They will kill only the young calves, but never the adult cows.
No. Cows are herbivores, not carnivores, so they don't eat stillborn young.
