How could i best answer these spanish speaking questions?

There is no "best" answer. You should just give your own opinion about these matters, and only you can know this. I am sure you will be able to use the verb "deber" a lot. Most of the answers can be given in the present tense, in the same way as the questions. Only the ninth question uses the second conditional and the subjunctive, so with that one you ought to describe what you "would do" with a friend.
