There are some tiny variations because of the tilt of the earth, but we can say that days and nights are roughly equal at the equator.

On Equinoxes
no
This is called the "equinox", or "equal nights" - when the night and day are approximately the same duration.
The seasons are already figured out . . . the seasons change on the equinoxes (days and nights of equal length) and on the soltices (days and nights are the most different in length)
June 21st is the summer solstice in the Northern hemisphere, and for the northern hemisphere it is the longest day of the year. In the Southern hemisphere June 21st is the winter solstice. This means it is the shortest day of the year. This happens due to the earth's 23 degree tilt. The equator, however, is right between the hemispheres. So the days and nights are of equal length.
Anywhere around the equator, the days and nights are always about equal.
At the Equator at the two Equinoxes, Spring and Fall.
On Equinoxes
Ther sun spends more time in the northern hemisphere, thus longer days and shorter nights. This is reversed when the sun spends more time in the southern hemisphere. At the equinox days, the sun spends time at the equator and the days and nights are equal.

Yes
it is 600 miles south of the equator
no
4 days/ nights and 18 hours
Any place on earth that lie on the equator will have equal day and night time.
Africa is a very large continent, with parts in the northern hemipshere and part in the southern hemisphere, so the equator goes through it. The parts closest the equator experience no real difference in the length of days and nights throughout the year. Parts of Africa that are futher from the equator do experience a difference. There is a lengthening and shorterning of days. So it depends on where you are in Africa and the time of year.
This is called the "equinox", or "equal nights" - when the night and day are approximately the same duration.
