Yes, it MAY be allowed. The "age of reason" for children in most states is usually set at, or about, 7 years of age.

Yes, if it doesn't violate the rules of evidence.
A judge has final say on what is or is not admissable in their court. The only recourse if the evidence was refused is to file for an appeal and have the appeals court see if his/her refusal of the evidence was justified. If they find in favor of the judge, you're out of luck. If on the other hand the appeals court decides the evidence should be admissable, the case will most likely be retried with the new evidence presented.
Although the use of polygraph results as evidence in court is regularly challenged - it IS a useful tool and is used in the preliminary stage of many criminal investigations.
No.
It will depend on the evidence, but probably yes. In most cases the report is not the entire recollection of the police officer.
Yes, if the evidence has already been ruled admissable in court, it can be used again. The more evidence that proves the point, the better.
If it used to quote a necessary piece of overheard dialogue, or to quote what a defendant or other principal in the case said, yes. To simply testify and/or use it in everyday court conversation and answers to other questions, no, it is not.
No, definitely not. Except for extremely narrow and defined circumstances, affidavits are considered "hearsay" and are not admissable as 'best evidence." Best evidence would be the testimony. in person, of the individual who gave the affidavit. Such a personal appearance allows the opposing side to cross-examine the witness. You can't cross-examine a piece of paper.
Slap her one. >:D no, but really.. As the Childs grandparents you can actually take your daughter to court, If it is in the Childs best interests to see you. It is all up to the child.
If the court has said you are to pay child support, your marital status does not matter.
