Your answer depends on where you are.
At the South Pole when the Earth is tilted toward the Sun, it's summer.
The South Pole begins its tilt toward the sun on June 21, which marks the first day of summer in the Northern Hemisphere.
At its full extent, the South Pole is tilted about 23.5 degrees toward or away from the Sun.
There is only one axis and it is always tilted. The part of the axis we call the 'north' pole is tilted toward the sun in the northern summer, and the 'south' pole is tilted toward the sun during the southern summer. That said, the earth itself is a little closer to the sun during the southern summer/northern winter.

Fall or winter.
Summer in the southern hemisphere -- when the South Pole is tilted toward the the Sun, it's winter in the northern hemisphere -- including the state of Florida.
Southern Hemisphere's summer season.
Summer in the southern hemisphere, winter in the northern.
At its full extent, the South Pole is tilted about 23.5 degrees toward or away from the Sun.
Its the season of winter.
the Southern Hemisphere is tilted away from the Sun, both the Southern and Northern Hemispheres are tilted toward the Sun, the Northern Hemisphere is tilted away from the Sun, and the Northern Hemisphere is tilted toward the Sun.
it is winter in the northern hemisphere
Summer
It is - every winter (in the north).
The 'equinoxes' occur in March and September. At those times, neither pole is tilted toward or away from the sun. At the time of the June solstice, the north pole reaches its maximum tilt toward the sun, whereas at the time of the December solstice, the south pole is at its maximum tilt toward the sun.
No, that would be impossible, because the Earth is basically an orb -- round. When the South Pole is tilted toward the Sun, it's summer in the Southern Hemisphere -- and Winter in the Northern Hemisphere.
