No one can say for sure- but jail time will be part of any sentence . It is best for your friend to retain an attorney and arrange to turn himself in. The court would look favorably at this- rather than if he gets picked up and arrested.
He needs a lawyer. If they have evidence of any of these charges, he'll get at least some prison.
Note that you don't give facts supporting a robbery (the worst charge you name). If the woman was not home or not threatened, this is first-degree burglary (still a strike, but better for sentencing that home invasion robbery).
This is exactly the type of case I handle. Please have you friend call or come in for a consultation.
Your question is a bit like asking, "How much will Facebook stock be trading at a year from now?" We can't predict the future and there are too many factors involved to be able to tell you the amount of time he'll receive.
I agree with my colleagues. He needs a lawyer, especially if there is a warrant out for his arrest. I also agree that some jail time, possibly prison time, is pretty much guaranteed with charges that serious.
