with your parents consent yes
No.
In some states-depends on adult age in yours
In my own opinion, I would wait until the sixteen year old is at least twenty meaning you (or the eighteen year old) would be twenty-two!!!! I think that right now you both are too young to call what you have love!!!!!! I wish you both the best of luck!!!!!
With parental permission, yes, she can.
Up to parents
Not in most locations in the world. The 16 will require permission from the parents. Or have a court order that allows it.
Only if they lied to get the marriage license. The 16 year old will require parental permission to get married. In a few states, the 18 year old will also need permission.
No. You must have parental permission to get married if you are under 18. Being pregnant doesn't change the age.
yes
That is up to the parents. There are no laws regarding dating. Both are over the age of consent in most places.
yes it is
No
