Both can make excellent pets. It depends on what you are looking for in a bird. If you are really big on teaching one to talk then a male would be a better choice but there is no guarantee that it will. Females can talk as well but not as clearly as a male. Otherwise I have found both genders to be easily trained and tamed and great birds to have .

you should look it up online and a whole bunch of pictures will come up.

No, I think that the male should remain in with the female to help her with the feeding of the babies.

Female parakeet may be aggressive and sighted the bird as a territory threat or vice-versa. Female birds become anxious if they have eggs
I don't think so. I read that adult female parakeets noses are brown and that adult male parakeets noses are blue. But, young female parakeet's noses are "bluish" and a young male parakeet's nose is pink.
Probably when they are very affectionate with one another or you have baby parakeets.
