How long will he go to jail if he does?

My brother is 19, has no respect for my mother. He still lives at home. No job, No car, No school and a kid which dss is now in the picture. I'm married with 5 kids. He is facing a couple charges at the moment.. all together he has Speeding, Felony Breaking and Entering. Felony Larceny after B&E. Aiding and Abetting. And last one assault with by strangulation with his babys mom. She is a complete fool and is trying to drop the charges, but the thing is the cops pressed the charges not her. They have pictures and statements from her. He goes to court in the morning for all 3 Felonys. the thing is.. They are going for a probable cause hearing with the B&E and Larceny. this is the second one they didn't have proof the first one. So do you think he will be going to jail for any amount of time? me myself and I prays he does but idk. He needs to get away from the crappy friends he has been hanging around and maybe will come out a man.. He is no longer allowed to see any of my 5 kids
