this one helps. If you know all your classes have a public parameterless constructor you can do:
manager[i] = (AbstractBaseClass)Activator.CreateInstance(manager[i].GetType());

How can I make a list or a dictionary with each element being a class instance?

I hope this helps . You are correct: Python doesn't have explicit private and public attributes.
I'm not sure what you're trying to do in the final for loop: you already have a list, except that you filled it with the class object itself, instead of instances. Try this:
self.__Questions = [Question() for x in range(self.__NumOfQs)]
for i in self.__Questions:
    i.SetQuestion()
