Legal question in california. urgent help!?

My brother(18 years old) recently was charged with embezzlement ($800) and conspiracy to commit a crime. A month before this incident he was charged with threat to terrorize, oral copulation, and with a foreign object with a minor. For this he was put on formal probation for 3 years. a 1500 fine, and 30 days jail. What are the possible general outcomes for his new case considering his prior conviction?
