1. If the person does not leave a will in which could be left everything to the female side and nothing to the male side. A will trumps that.also in many cultures the woman receives nothing.
2. Yes but in many cultures for thousands of years it's women who have had to pay it.
3. Polygamy is forbidden if you've read Baha'i literature. It was dependent on being absolutely just to all wives which is impossible and so Abdul-Baha said it really forbade polygamy
4. The reason will become self evident
5. All the Prophets of God have been men too we don't know why but I believe it's out of mercy not discrimination.
6 Women can go but they are exempted because it may be rigorous for them. Again mercy applied here not discrimination. Things like women having their courses are accounted for so its not made obligatory.
7. It's just a title. I see passages where Baha'u'llah exalts women over men.
"By My Life! The names of handmaidens who are devoted to God are written and set down by the Pen of the Most High in the Crimson Book. They excel over men in the sight of God."
8. They can both make out a contract specifying a virginity requirement.
In one of these cases you cite, for example, that of a wife who is found by her husband not to have been a virgin, the dissolution of the marriage can be demanded only "if the marriage has been conditioned on virginity"; presumably, therefore, if the wife wishes to exercise such a right in respect to the husband, she would have to include a condition as to his virginity in the marriage contract.(Universal House of Justice)
Here's some references to clarify a lot of the issues you appear to have misunderstood about the Baha'i Teachings.
