The hope of creating a cabinet system for the Texas executive branch would be that it would lead to greater accountability. Texas became a state in 1845.
This group is called the President's Cabinet.
There are many things that were not written into the Constitution, but can be interpreted from the document- For example, the cabinet and political parties.

The Secretary of Homeland Security is the last in line. The ranking is made in the historical order of the establishment of the Cabinet positions.
It means you're either a spiky cabinet or an extremely brilliant heavy metal band.
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.
I think Obama had one cabinet meeting during is first term. They took a group picture, so that may have been its purpose. I suppose making introductions was another reason and Obama may have said something abut the goals of his administration and what he expected from his cabinet.
The quote "life, liberty, and the pursuit of happiness" comes from the United States Declaration of Independence. This document calls these things unalienable rights.
