Second time in, absolutely no parole. He will do 85% of his sentence this time.

There is a sentencing date that can be obtained by contacting the Clerk of the Court of the county where they caught their charge. There are sentencing memorandums that both sides submit to the Court for sentencing recommendations. There are mandatory minimums that the judge has to consider, but nothing is known until the judge sets the sentence.

if he committed a crime in that state, he will do his time in that state, that is the law. he is FORCING them to keep him locked up because of what he did, not what they did

You can contact the Clerf of the Court in the jurisdiction where they were prosecuted and convicted. Ask to see the "Judgement and Commitment Order". This is where the lawyers go to get their documents filed and research the filings in the case. There might be a nominal fee to print out any information you are requesting.

There is more than one penal facility in Leavenworth (county, federal and military). The federal side has two separate facilities for different custody levels. The satellite prison camp is adjacent to the US Penitentiary and is by far a better location to have to do time.

He will do 85% of the 60 months (51 months). Every hour spent in confinement will go towards fulfilling this commitment order no matter the facility he's held in. 

This is not a good scenario. The DUI could cost him a lot more time behind the wall, probably not "life", but if there were any injuries or property damage it could be significant time.

Possession of a controlled substance less than 1 gram is a state jail felony with a punishment range of 6 months to 2 years state jail (no parole from state jail) and a fine of up to $10,000. Due to the overwhelming number of state jail dope cases, the law requires probation in many cases.

The designation for commitment is determined by the Department of Corrections. They will base the security classification on a number of factors including their criminal history, the type of crime they are convicted of, the value of the crime in dollars, was there any violence, and was anyone injured or any involvement with a gun. 

I did time in FCI Miami with a few guys that were caught off the coast smuggling immigrants and they got five years in federal. With a "bad past," it might be more because they use the negative history against you at sentencing.
