it isn't always the same, but genorally four. the wind turbines used for generating electricity however, usually have three
Windmill vanes are called blades or sails. These are attached to the rotor of the windmill and capture the wind's energy to generate power or perform mechanical work.
The sails on windmills turn when they are hit by the wind. The force of the wind causes the sails to rotate, which in turn drives the machinery inside the windmill to generate power or perform mechanical work. The design of the sails is crucial for capturing the wind efficiently and converting it into rotational motion.
There may be a small propeller on the opposite side to the main sails or there may be a vane to turn the windmill. See the examples in the links below.

It depends on the wind and the rating for the windmill
The measurements of a windmill can vary depending on the size and design. The typical height of a windmill can range from 20 to 80 meters tall, with rotor diameters ranging from 50 to 120 meters. The size of the tower, blades, and overall structure will depend on the power output and location of the windmill.
A windmill is a building with "sails."
I don't think there is another name other than blade.

A Dutch building with sails is commonly called a windmill.

A windmill does not blow.A windmill is blown by the wind.The windmills sails turn the wind into power to operate machines, pumps or electrical generators.

The design of the sails is crucial for capturing the wind efficiently and converting it into rotational motion.
The angle of the sails of a windmill, commonly referred to as the sail or blade pitch, can vary depending on the design and purpose of the windmill. Typically, the angle is set between 10 to 20 degrees to optimize efficiency in capturing wind energy. Some modern windmills may have adjustable sails to adapt to changing wind conditions, enhancing their performance and energy output.
A windmill, like in the Netherlands.
The wind blown in the fantail turns the main sails to point to the wind.
A tower mill is a type of vertical windmill consisting of a brick or stone tower, on which sits a wooden 'cap' or roof, which can rotate to bring the sails into the wind.
