he fact that you are found not guilty of a crime is not a basis to sue. DAs make charging decisions based on the evidence. A not guilty simply means that the jury saw it differently. On the other hand, if you could show that the prosecutor intentionally counseled witnesses to lie, you could sue. That would be a very difficult thing to prove and I doubt many lawyers would agree to take that case.

If he was guilty, the arrest was likely with probable cause, there was probable cause to prosecute, and there would be no damages for any misconduct.
When you say that state's witness committed perjury, you need to give more detail. Many people believe that witnesses commit perjury when their testimony isn't believed. Using that reasoning, witnesses would need to be charged with perjury after nearly every trial. If you mean that they intentionally lied, then they are a complaining witness and they caused a malicious prosecution and mey be liable (though as another attorney has mentioned they may have no assets).
The description of the prosecutor's conversation with the witness sounds like a misunderstanding of a conversation in which the prosecutor may have said that they don't care what the witness said so long as they told the truth.
In any event, if your friend is innocent and the witness lied, then your friend should talk to a lawyer.
