I strongly suggest you see your physician, and ideally a cardiologist, so as to assess the condition of your heart.
Go to the doctor. This is not the forum to get an answer on this problem.
You could have unstable angina. Heart pain on exertion. You should see a doctor.

It does not hurt an engine to run it with no exhaust muffler
No, it would hurt. I don't think you would like someone hit you in the chest.

it depends on how much fat is on your chest. my answer would be to run everyday as much as you can.
Some signs that you need a bra are that your breasts are growing, if you notice things changing go ahead and start with a training bra. If your chest or shoulders hurt when you run or participate in gym, you need a bra.
