prime minister
finance minister
The president calls and presides over any cabinet meetings. My understanding is that President Obama has called only one or maybe two cabinet meeting since his term began in 2008. The president is , of course , the boss over the cabinet if that is what you are asking.

vice president
No. The Speaker of the House (of Representatives) presides over meetings of the US House of Representatives. The Vice-President of the United States presides over meetings of the US Senate .

The President Pro-Tem presides over the Senate when the Vice-President is not there. The Vice-President barely attends Senate meetings anymore.
The President of the United Nations General Assembly presides over its meetings. This position is typically held by a member state representative elected by the General Assembly for a one-year term. The President is responsible for maintaining order during debates, ensuring that the rules of procedure are followed, and facilitating discussions among member states.
Assembly speaker
The "chair" is the person who has been delegated to be in charge, creates agendas for meetings and presides over such meetings as a facilitator to keep the subject matter on topic.
