Yes they do, but they will go back to normal (well an adult version of normal) before puberty is over.
Yes, it is a common procedure
Surgery is the only thing that helps.
Yes. Nipples grow larger when women start puberty... If a 10 year old girl hasn't started puberty, her nipples will be small
I think we might need a picture for an accurate quote. There can be so many variations.
no
It's part of puberty .
Large, erect nipples are seen as being very sexually attractive. Perhaps this comes from women finding it very pleasureable to have their nipples played with, causing them to become even more erect, and making the vagina and clitoris highly prepared for more activity, thus causing the desire for additional sexual activity, often including intercourse. Correspondingly, women's nipples may have gotten larger through time as a response to this... perhaps the women with the largest nipples were more sought after as sexual partners.
It could be puberty.
The nipples do tend to harden a little once Puberty has begun so it should be nothing to worry about. If you are concerned then visit your Doctor who will examine them for you.
