That all depends on when they have been bred. A heifer bred at 15 months of age would calve when she's 24 months old. If she's bred later than that, she will always calve 9 months later.
no
A cow is pregnant, or 'in calf', for approximatly 40 weeks (9 months).
none or one
Depends on how many lions and how many elephants are present. If it is one-on-one, I'd say elephant. It takes a whole pride of lions to take down an elephant, even a calf.

How ever many months it needs to carry that pointless life.
One at a time..the gestation period is very long. The elephant's gestation period is 22 months, the longest of any land animal. At birth it is common for an elephant calf to weigh 120 kilograms (265 lb). That would mean that ,technically, they could have an baby elephant every 2-2 1/2 years until the elephant reaches about 45 yrs old. If you mean how many in a lifetime of an elephant...depends on the elephant...elephants have a life span of up to 70 years. If the elephant is in a zoo, life span is about 35 years.
Other than in a very rare case of twins, only one elephant calf is born at a time.
A typical female elephant will give birth to around 7 elephant calves during her lifespan. The gestation period for an elephant is nearly two years, and and elephant will typically give birth every 3-6 years.
22 months is the gestation period.
