A double pupil is a condition a person may be born with. There is a smaller pupil or opening adjacent to the normal pupil. It is still located within the iris and does not affect one's vision. This in old times was known as a "witch's eye".

The choroid layer in the eye has a black color pigment on it. Also, the light entering the eye is not reflected because light rays entering the pupil are absorbed by the tissues inside the eye.
The pupil of the eye appears red in some photographs because the light from the camera flash reflects off of the retina at the back of the eye. The light reflects red because of the blood vessels at the back of the eye. This light sometimes comes back out of the pupil and shines through the lenses of the camera. This can be prevented with a red-eye reduction feature of the camera. This will give a couple warning flashes before the picture is taken, causing the pupil opening to narrow and thus reducing the chances of light reflecting back out of the eye.
