Hi
First of all be calm and cool...this or any other kind of battle can only be won with a calm mind. Getting irritated or frustrated is natural in any kind of court proceedings but try controlling yourself.
Now
1. Hire a good lawyer
2. Get the bail done again
3. Appear on all the court hearings
4. For the job of your father... any govt department cannot releave an employee from his job unless and untill he is held guilty in any criminal case. As per your description your father is under trial and not held guilty till now. So file application for rejoining the job in the higher authority or take shelter of court.
5. Defamation case will not be of any help to you. Gather proofs of your favour and concentrate on the pending cases.
6. Try taking the matter to Mutual Consent Divorce.
7. Simple injuries can lead to punishment. But max.6 months (depending upon nature of injury and way the advocate handles the situation).
8. If she can't prove the allegations made by her then keep cool.....you will be free soon.
All the best
