No. Judges cannot overturn when you have been found not liable.
It is called the verdict. In a criminal case it will be Guilty or Not Guilty. In a civil case it will be Liable or Not Liable.
Appeals in civil cases are generally not easy to overturn; appellate courts typically defer to the jury's findings unless there is a clear legal error or substantial evidence issue. The appellate process focuses on whether the trial was conducted fairly and according to the law, rather than re-evaluating the evidence. As a result, a successful appeal usually requires showing that the trial court made a significant mistake that affected the outcome.
There probably aren't statistics for the whole country, but a judgment not withstanding, such an occurrence is rare.
I am going to assume this has to deal with criminal law as it is in the "Crime and Criminal Law", so this information does not apply to civil (Though it is similar). The good news is that if a jury returns a verdict of not guilty, that is it - the defendant is not guilty on those charges. It can never be overturned (Assuming there is not some type of jury problem and there is a retrial). Basically, an appeals court can never overturn a not guilty verdict when it is returned by a jury. This is based on the doctrine of claim preclusion. If someone could be tried twice on the same charges, this would be a deprivation of the 14th amendment due process right afforded to the defendant by the state. There are some instances to take note of, however. One being when the jury returns a guilty verdict, and the judge grants a motion notwithstanding the verdict (Essentially overturning the jury's verdict and finding the defendant not guilty). This CAN be appealed and overturned. This is not subject to claim preclusion. Good luck.
In civil cases, a jury decides the outcome based on the evidence presented in court. Jurors listen to arguments from both sides, evaluate the facts, and reach a verdict on whether the defendant is liable or not. The decision is typically made by a majority vote of the jury members.

No. Civil is majority must agree.
The laws that govern appeals in Washington are the Rules of Appellant Proceedure. To go through them all here is not possible - although you may refer to your local library for a copy of WA state laws, or utilize a search engine.
It depends on the state
