Here only 2 and 5 are correct.. 3 is not correct because a class can never extend a interface it only implements any number of interfaces. And here 2 is correct because a class can extend only one class but implement many interfaces.

3rd statement is correct because there is no parent class for interface. In case of a class , the super class is object class.
Ex: class A extends Interface1, Interface2, Interface3..... Hence multiple interfaces can be inherited.
