This is a legal question and an attorney should be consulted, however, visitation should be attainable, but full custody of one child, removing her from the family home where there are siblings would be doubtful. Unless there are compelling reasons for the child to be removed and custody given to the birth father, like abuse, the chances of full custody are nil.
Her mother
that depends on if the mother has custody over her daughter or not. It also depends on how old the daughter is. If she is under the legal age limit, then the mother is still responsible and makes all decisions for her. If the mother does not have full custody over the daughter, then the mother and the father of that child must come to an agreement on the living whereabouts of the daughter. If the mother has legal custody over the daughter and the daughter is not of legal age yet, then yes, the mother can bring the daughter over too.
For 1) are you in custody of your daughter? If you are in full custody you could take her to court for kidnapping is your EX mother in law in custody of your daughter? Do you have joint custody? If your ex mother in law has no custody over your daughter you could take her to court, she is not authorized to take care of your child.

Assuming Dad has custody, then he would have to agree to let daughter move in with you OR you would have to petition the court for a change of custody.
YES, IF SHE HAS SOLE CUSTODY OF THE CHILD AND THERE WAS NO AGREEMENT TO STAY IN THAT STATE. OR IF NEITHER PARENT HAS LEGAL CUSTODY EITHER PARENT COULD DO THAT
You have to be established, legally, as her biological father so if you have not done that do that first. Have DNA tests done if needed. Then you can apply for custody or visitation rights.
