Yes, a girl can get pregnant before she reaches menarche. Menarche is first menstruation, and menstruation only occurs as a result of ovulation if the egg is not fertilised.

The same thing that causes pregnancy after menstruation: sex.
Yes, of course if you were to get pregnant you'd not menstruate. Menstruation only occurs when you don't get pregnant.
Typically no, a woman can't get pregnant a week before menstruation. Typically ovulation occurs two weeks before menstruation, at most there is only a viable egg present for 48 hours. It is possible for the luteal phase between ovulation and menstruation to be shorter, for example a week shorter and thus ovulating a week before menstruation, however such a short luteal phase wouldn't give the fertilized egg enough time to implant.

Immediately after menstruation it is possible to get pregnant. It is even possible to get pregnant during menstruation, though very very very unlikely. It is always possible for a woman to get pregnant as long as she has a healthy, pre-menopausal, post-pubescent, fully functioning uterus and is having sex with a man in a similar situation. However, women are more likely to get pregnant right before their period and less likely to unlikely to get pregnant during or after their period.
No, you can't get pregnant one day before your period and you wouldn't be abler to menstruate if pregnant. Ovulation typically occurs two weeks before menstruation, it then takes time for the fertilised egg to travel down the fallopian tubes to implant in the uterus. During this time hormones change to let the body know about the pregnancy in order to stop menstruation.
You ovulate two weeks before menstruation - thus the soonest you'd skip a period is that first period, two weeks after you get pregnant.
Women are most fertile about 14 days before the start of their period.
