Between 23.5° south latitude and 23.5° north latitude.
The sun is directly overhead between the Tropic of Cancer (June) and the Tropic of Capricorn (December) when it's rays are most intense. They are least intense at the South Pole (June) and North Pole (December).
The tropic of Cancer is 23° North of the Equator. It represents the point where the Sun can be directly overhead. If you are any further north, the Sun can not be overhead. The corresponding feature in the southern hemisphere is the Tropic of Capricorn. As to the Sun's direct rays, they can be anywhere from the South Pole to the North Pole. Those two points and everything in between receives the Sun's direct rays at some time during the year.
Yes on one day in the year the solstice denoting summer in each hemisphere.
At the equator at the equinoxes, and at some point between the two tropic latitudes (Cancer or Capricorn) the rest of the year.
No. The sun can never be overhead at any latitude that's more than about 23.5 degrees north or south. (What's the matter ? Doesn't Houston get hot enough for you in August ???)
At either of the tropics the sun's rays are most directly overhead at mid-day in mid summer.
The sun's rays are always directly overhead somewhere on earth. Twice a year,at the moment of each equinox, that place is somewhere on the equator.
When the Sun is DIRECTLY overhead its Rays are the strongest. This is because they are traveling through the shortest amount of the Atmosphere to reach you.

There is no time between these. On the day before the autumnal equinox, the sun is directly overhead in the northern hemisphere (at a latitude just north of the equator). The following day, it is directly overhead in the southern hemisphere (just south of the equator). The sun goes from being overhead in the northern hemisphere to the southern hemisphere instantaneously, the change happening at the autumnal equinox.

The sun is directly overhead on the Tropic of Cancer at the timeof the June solstice ... roughly June 21 or 22.
Only between 23.5 degrees on each side of the equator. The earth is tilted at 23.5 degrees, so the sun's vertical rays will only oscillate between those latitudes throughout the year. They are at those extremes during the solstices.
At the equator at the equinoxes, and at some point between the two tropic latitudes (Cancer or Capricorn) the rest of the year.
The Earth is close to a sphere so there is but one single point on the sphere that has the Sun directly overhead at any one time. When this point is in the Northern hemisphere (roughly from the 21 of March to the 20 of September) the Southern Hemisphere is less directly hit by the rays of the Sun and experiences somewhat cooler seasons than when the rays of the Sun strike more vertically.
