This all depends on the age that the calf was weaned and its breeding. Sex is irrelevant for this question, though heifers tend to weigh around 25 to 30 lbs less than bull or steer calves.
British beef calves can weigh around 500 to 600 lbs when they are weaned around 6 months of age; when weaned at around 10 months of age, they can weigh around 750 to 800 lbs. Continentals on the other hand, will weigh around 700 to 750 at 6 months of age, and up to 900 lbs if they aren't weaned until they're around 10 months of age. Beef calves that are weaned earlier will weigh less than those that are weaned between 6 and 10 months of age.
Dairy calves, which are weaned off the bottle or bucket, are often lighter. Holstein and Brown Swiss calves, when weaned at 3 months of age, will weigh around 200-275 lbs; Jersey calves weaned at the same age will more often weigh only 150 to 200 lbs.
Remember thus: The smaller the calf, the lighter the weights. The earlier the calf is weaned, the lighter the calf will weight. And vice versa for both.
Only if that calve has or is being weaned.
A bullock or young bull. It can also be called a bull calf if it's a pre-weaned calf.
Between 2 to 6 weeks.
The problem is there is none. You have to go by the calf itself and the body condition of the cow (as well as markets and your management practices) to see whether it is good enough to be weaned off milk or off its dam A dairy calf is weaned off the bottle at around 3 to 4 months of age (some may want to go a little longer), and a beef calf can be weaned from its mother anywhere from 6 to 10 months of age. Beef calves may need to be weaned at 3 to 4 months (called "early weaning" if drought conditions do not allow a cow to provide enough forage to make milk for her calf. So it's all up to you and what you consider what age is "perfect" to wean a calf.
No. This is too early to wean a calf. If it's on the bottle, it should be weaned at around 3 to 4 months of age.
Most calves are weaned by this time, thus may be still called calves, but others may call them heifers (if female), bulls (if intact) or steers (if castrated).
Almost immediately if that's the purpose of the calf--for meat and not breeding.
That all depends on the age, weight, condition and type (beef or dairy) of calf. Are you referring to baby bottle calves, or feeder beef calves that have been weaned? It is that kind of information that is needed to be able to answer this question. A bottle calf can be sold for as little as $10, and a beef calf that has been weaned that weighs around 600 lbs may go for as much as $500 to $800 (sometimes more) depending on current prices.
He should be weaned at around 3 to 4 months of age.
First of all, there is no such thing as an adult calf. A calf is no longer a calf after he/she is weaned. After a calf is weaned, she would be called a heifer. If it's a male, then he would be called a steer (if he's already been castrated) or a bull (if still intact or uncastrated). A heifer becomes a cow after she has had at least two calves. When she has her first calf, she is commonly referred to as a first-calf heifer.

Around 6 to 8 months of age.
A bullock or young bull. It can also be called a bull calf if it's a pre-weaned calf.

A calf is a general term for an immature bovine that relies on its mother or the bottle for milk for several months of its life until weaned.
