You can, but there is a high likelihood that you will be picked up

What are the odds that she gets stopped for a traffic violation? They aren't going to send the US Marshal to find her, but if she screws up, they will have a reason to detain her and notify the county in Oklahoma that issued the warrant. It's not a felony to not pay a fine, there is surely more to this story...

Are we talking arraignment, bond hearing, pleadings? You are entitled to a speedy trial but that is not generaly defined to a time frame. We know some defendants that could not make bail sit in county jail for 6-9 months before anything happened on the case.

First offense, marijuana and paraphernalia? This could be settled with a pre-sentence intervention where your fiance pays a fine and goes to class for a few days. There is probably no way to get it "erased", as that is his record now, unless this intervention comes with an expungment too.

That is a very serious charge and before you "get involved" any further, maybe you should get some legal advice. If he was accused of something you sent, you might put yourself in a position to defend yourself. Forget about saying, "you had nothing to do with it", all the inmates there are innocent, too

If this is a federal charge, you can Google your inmate's name with the word "indictment" to see the FBI's statement on the charges. They love to brag about their conquests so there is no lack of publicity.   If neither of these work, you can use a pay service that has the most accurate and up-to-date arrest information nationwide.

You will risk exposing yourself to detainment if you have an outstanding warrant. We would recommend writing as a first option, maybe through our letter service if you wanted to avoid using your name. If you go the calling or video visit route, you are giving the authorities your location. Why not work out something with the jurisdiction that has the warrant and turn yourself in. It's not going away and it'll be easier to deal with than if you

You need to contact the Clerk of the Court in the state and county of his arrest. They will have the exact charges. If he is not able to afford an attorney, one will be provided. The timing involved in that process varies depending on the public defender's office.
