Yes. At the beginning or the end of the cycle. If it's brown for the entire time, you may have a vitamin deficiency (iron). Check with a doctor. It could be a sign of something else.
The term menstrual cycle refers to your entire reproductive cycle, I think you mean menstruation or your period. Menstrual flow can be brown when it is light as it takes time for the blood to leave the body and it goes brown as it gets old, it also mixes with discharge which changes the colour too.
It is dried blood and very normal for your body to get rid of it at the end of your menstrual cycle.

Not more than a tiny amount. Menstrual fluid is not blood, but disintegrating cells.
Basically, menstrual 'blood' is not just blood, it's the remains of the tissue that has built up - so it is not unusual for it to come in a different colour than normal, red blood. Chances are it means absolutely nothing :)
It may be brown sometimes. The brownish blood is just the old dead blood cells you dont need in your body.
Yes, a 45 day cycle is still considered normal. The average menstrual cycle is 28 days but everyone is different and as such a longer cycle is perfectly normal.

It turns brown because it's old "dead" blood. Black would probably be the clots associated with heavy bleeding usually seen at the beginning of a cycle.
No.
yes, its just the bodys way of getting back to normal.
