What do you want to inherit from what?
This is the important question, because Inheritance is only usable if the structure of your classes makes it so.
For example, you might create a base Car class, and inherit from that to produce Manufacturer classes: Ford, BMW, Mercedes - because you don't "buy a Car" you "buy a Ford" or "buy a Mercedes".
And you might derive "model" classes from the Manufacturer: "Escort" could inherit from Ford (and thus from Car as well) and "EQS" from Mercedes in the same way.
To use inheritance then isn't difficult: Java - Inheritance - Tutorialspoint
But your models so far are all totally unrelated: there is no obvious link between them, so no obvious base class or derived classes to inherit from them!
