Parakeets can get noisy but if they have the right amount of attention and care, they shoud not be much of a bother. Female parakeets make less noise(practically none) than males but keep in mind that females are much more aggressive. Alse, at night, keep their cage covered with a sheet or towel and that should keep them quite while you are sleeping. I hope this is helpful.
Yes, they do.
As many as you can handle. Parakeets tend to make a lot of noise and take a lot of care. Often you are best to have two pairs, because they like to keep each other company if you're not around to entertain them.
