If one is tried for a crime and is found innocent, one may not be again tried for that crime because of the principle of double jeopordy.

A person is never found innocent. A person is found guilty or not guilty at the verdict phase of a criminal trial.
Depends. If it is not a trial for a very serious offence, then once found innocent then that is the end of it. If you were on trial for an offence such as murder, then under the new "double jeopardy" rule you may be re tried if significant evidence comes to light.
Assuming you're asking about Chase's impeachment trial in the Senate, he was found not guilty (no one is ever found innocent) of the charges against him in 1805.
That is double jeopardy, and it is not legal to do.
A fair trial in court. Innocent until proven guilty.
If your charges were DISMISSED before you went to trial, then your charges were simply dismissed. However if you went to trial, there is no such finding as "innocent," the only verdicts are 'guilty' and 'not guilty.'
only if you are silly enough to commit the same crime another time
This is when you reject a null hypothesis even though it is actually true...Example:1. A man is on trial for murder, he is actually INNOCENT, but found GUILTY - That is a Type I error2. A man is on trial for murder he is actually GUILTY, but found INNOCENT - That is a Type II error
