No; the change in the size of your pupil is an involuntary action, meaning that it happens without you thinking about it. The size of your pupils adjust to stimuli, such as bright light.

Reversely, if you're in a dark room, your pupils will get bigger to let in as much light as possible.
No. The pupil can only open to the size of the iris.
The iris is the layer that surrounds the pupil and controls the size and diameter of the pupil. It also controls the amount of light that reaches the pupil.
