The menstrual cycle is the reproductive cycle, as long as she is fertile she is always on her menstrual cycle. You can't tell where she is in her menstrual cycle unless she tells you.
You can tell if your menstrual cycle is irregular because you'll be menstruating or experiencing vaginal bleeding at random times. Anything up to a weeks variation from your average menstrual cycle is considered to be normal, if there are weeks or months difference then they're irregular.

No, having multiple sexual partners has no impact on the menstrual cycle at all.The menstrual cycle is the reproductive cycle, it is controlled by hormonal changes within the reproductive organs and so sex does not change the cycle (unless the person falls pregnant). The menstrual cycle can't tell how many sexual partners a person has, nor would there be any reason for the menstrual cycle to change if a person has multiple sexual partners.
It's possible, but there's no way to tell that isn't insanely expensive and uncomfortable.
When you ovulate depends on your own menstrual cycle and it can change from one cycle to the next - you can sometimes tell when you are ovulating with testing kits but monitoring your cycle with fertility awareness method is the best way to determine when you ovulate. During a typical 28 day cycle a woman will ovulate 14 days BEFORE menstruation, which would also be 14 days into the menstrual cycle (the first day of your period is day one of your menstrual cycle).
Not possible to tell.
