My question involves criminal law for the state of: Michigan

A 33-year-old male acquaintance (not friend; don't know him well; we volunteer at the same non-profit) was arraigned on 5 counts: 1. assault with a dangerous weapon, 2. aggravated domestic violence 3. domestic violence, 4. aggravated assault, 5. malicious destruction to a building less than $200. Allegedly he broke his girlfriend's nose and she had to go to the hospital. Her mother was also somehow involved though I don't know how; I don't think she was hurt.

I know cases are often plea bargained. May I ask, what is a ballpark sentence he might receive? I've looked up the basic sentence guidelines for each offense but don't know how these might be combined in this case. Thank you for any feedback.
