Yes, this is normal. The nipple stretches as the baby sucks it towards the back of his/her mouth to draw the milk from the breast. The nipple will soon return to its normal shape.
Yes, it is normal. There are very small openings on the nipples to allow breast milk to flow during lactation and breastfeeding. Males can also have small openings, but it is not as common to be able to actually see any of them, because of the difference in size of the nipples, being so small.
An inverted nipple is a normal variation in most people. It's a nipple that is "flat," that doesn't stick out.
Sorry to say but the nipples will never go back to look like they did before pregnancy and breastfeeding. Every woman's body is different when it come to pre-pregnancy and post pregnancy, however, my sisters went back to "normal" about 4 months after. Mine still hasn't yet, but i'm barely 2 months post. I'll update in 2 more months.
Those bumps are called the Montgomery glands and they act to moisturize the nipples, especially during breastfeeding. See related links for more details.
Yes hairy nipples are normal for Men... but for girls they usually dont grow hair around the nipples.

Both breastfeeding and the contraceptive implant can prevent bleeding.
I definitely think you should see your doctor, it could just be REALLY dry skin which has caused your nipples to crack open and possibly be more sensitive. or it could be serious. How long has your nipples been like that?
