Winter in northern hemispere
Yes.
On a solstice, it is only at the equator that the hours of light and dark are equal. At other parts, they would be different with one of the Poles experiencing 24 hours of daylight and the other Pole experiencing no daylight. If it is the June solstice, then it is the North Pole with 24 hours of daylight and the South Pole with none, while it is the opposite in the December solstice. It is at the equinox that the amount of daylight and darkness hours are equal around the world.
There are 24 of them.
90° north latitude (the north pole) and 90° south latitude (the south pole)
It depends on your location on Earth. At the south pole, there are 0 hours of daylight on June 21... until ~13,000 years from now when the Earth's axis of rotation will precess to give it summer in June.
On June 21, the arctic circle, which is located at 66.5 degrees north latitude, through the north pole at 90 degrees, has 24 hours of daylight. On December 21, the antarctic circle, which is located at 66.5 degrees south latitude, through the south pole at 90 degrees, has 24 hours of daylight.
At the south pole, December is the middle of a continuous period of light that began on September 21 and lasts until March 21. Since December has 31 days, there are 744 hours of daylight there in December.
On December 22, all regions at or below (towards the south pole) the antarctic circle will have 24 hours of sunshine.

Yes, for the six-month period between its sunrise about September 21 and its sunset about March 21 the daylight time lasts 24 hours at the South Pole. The same is true at the North Pole, and the events occur on the same days, in opposition.
Twelve hours of daylight on the Antarctic continent would be a phenomenon experienced in a narrow, circular band of geography between the Antarctic Circle and the South Pole. This phenomenon would occur midway between December 21 and June 21, and again between June 21 and December 21.
The sun rays are on the Tropic of Capricorn on December 21 and it leads to winter in the northern hemisphere and summers in the southern hemisphere,because on December 21 there is 24 hours of daylight on the south pole, south to the antarctic circle and 24 hours of darkness on the north pole, north to the arctic circle.
There is one sunrise at the South Pole each year, which occurs about September 21. From then until about March 21, there are 24 hours of daylight every day until the sunsets. This is caused by the Earth's tilt of the Southern Hemisphere toward the Sun.
