A cow can deliver one calf at a time.
One. Twins occur in one out of 1000 births.
Cows can have one or two calves at a time. Odd time she'll give birth to triplets.
Most cows will give birth to a single calf. However, twin calves are not uncommon. I do not believe it is physically possible for a cow to have triplets, though.
A moose can give birth to one or two calves at a time, with the average number of calves in its lifetime varying based on factors such as survival rates and reproductive success. Generally, a moose can have between 4-10 calves in its lifetime.
Neither. Both calves will be fertile. You will only get a sterile female calf if she's born to a twin bull brother.
Always one. I've never heard of two calves being born at the same time; if there were twins, it's always one after the other, as the cow's pelvis is only wide enough to allow one calf through at a time.
2-4 calves

Camels only have one calf at a time. Having twins is unheard of.
Asian Elephants normally give birth to one calf at a time, but there can be twin calves. Elephants can give birth to about 7 calves in their lives.

Usually one calf per cow. Occasionally one cow may have enough milk to feed two calves, but dairy nurse cows can have as many as four calves suckling from her.
Do you mean, "How many other calves are delivered at the same time as a young bull?" Either zero or one, usually.
