1. No based on the information provided.
The key is you can't ask them, explicitly or implicitly, to leave with you.
It is fine if they do that on their own.
2. Possible. As a matter of fact, you are going to get one anyway if this happens, regardless you have breached the contract or not.
It is somehow a standard procedure.
3. Yes.
4. The lost income due to students' leaving. It will be a large amount in your case.
I understand that this sounds stupid - you should get your current employer to get involved earlier, not after your departure. In this case, your employer will be put on notice that you don't ask them to leave, but they choose to leave with you. In that case, your employer can work on retaining the students. If they fail, they can't blame you.
