Since you have asked multiple questions, we will solve the first question for you. If you want any specific question to be solved then please specify the question number or post only that question

Current is defined as the rate of flow of charges. The charges flow from a region of higher concentration to a region of lower concentration. Even though electrons are the charge carriers in metals, we consider the direction opposite them to correspond to the direction of the flow of positive charges. And this is directed from the higher potential (more positive charge) to lower potential (more negative charge)
