Different cases regarding qisas and punishment of non Muslim slaves

As Salam alaykum. I have several questions regarding different matters that i'd like to understand. First is the punishment of Non Muslim slaves I'd like to know if they were punished according to Shariah when they drank/ate pork/committed zina/stole or did anything that was against islam even if that thing was allowed in their religion or where they punished according to their religious rules like the free dhimmis who managed their affairs between themselves? Or even, were these non Muslim slaves allowed to drink and eat pork and do whatever was allowed in their religion? The second question is about if qisas is applied on different people like when a master unjustly kills his slave, is he killed in return? If not, why? If not killed, is the master obliged to pay diyah money to the relatives of the slave if they are free people or slaves? Is a slave punished by death if he kills his master for defending himself against an injust attempt at murder by the master or attempt at abusing him physically or for an unvolountary murder of the master, like an accident? Also I'd like to know if a parent can be killed if he kills his child willingly and if the child as a minor and as an adult is killed if he kills his parent? Because I've seen that a parent isn't killed for killing of his child and a master isn't killed for the killing of his slave even if it was a voluntary murder and I'd like to understand why the status of a parent and a master prevents the Qisas? I'd like to understand also if a leader can be killed for killing someone injustly or if his statues as a leader also nullifies the Qisas? Jazakum'Allahu khayran if you take the time to answer all my questions 🤲
