No. You should only capitalize proper nouns so presidential is not capitalized. But if you are talking about the President as in "The President refused to comment" then it should be capitalized. However, if you are talking about presidents generically as in "no one is really sure who was the first president to...." then do not capitalize.
You can capitalize both.But you may only capitalize either of them if talking about a specific president or a specific vice chancellor.For example, if you are talking about "The President of the United States" that would be capitalized as it is specific and not general. Or if you were talking about, say, "President Obama" it would capitalized as you are speaking specifically about an actual president. Now, if you were to say, "When I grow up, I'm going to be the president!" It would not be capitalized because you are not specifically speaking of one certain president.Same thing for vice chancellor. If it is speaking of a specific person, it would become capitalized. If not, and you're simply saying something like said before. For example, "When I grow up, I'm going to be the vice chancellor of...!" And so forth. Other than that, vice chancellor would remain lower cased and not capitalized.
