Brake warning light started coming on with traction light?

I have recently been having problems with my vehicle listed above. A few months ago, brake lights started coming on along with my traction light. My mechanic friend took a look at my car and the only issue with the brakes was that the rotors needed to be replaced. Everything else was perfectly fine. He replaced the rotors, but the lights stayed on intermittently, sometimes when I’m driving, none of the brake lights will come on other times they will come on intermittently. Another issue that has started more recently has been that a few weeks ago my engine light came on while I was driving, and I felt an aggressive vibration of my car. This issue has also been intermittent as sometimes I’m driving, and my car is fine, other times I’ll go to accelerate, and the engine light will come on and my car will aggressively vibrate. My mechanic friend scanned my car for codes and codes for the ABS, AHB, ESP, and SRS systems popped up. What does this mean?
