Essentially does each cell think on its own? How does it know how to interact with other cells? Does it have any sort of intelligence other than do the one job it has? How does it know to have that job?

In the human body, immune cells come to mind. Some types essentially get to freely move around and monitor the rest of our cells to check that everything looks right. You can look up videos of white blood cells moving around and they look like little amoebas unlike most of our cells that are locked in as tissues.
Sperm cells are another cell type that can behave somewhat independently and are basically a separate organism (as they potentially become an offspring). In humans, our sperm aren’t that impressive, but if you look at other organisms that have *alternating generations* then their gametes get to go on and have their own little haploid lives before eventually fertilizing and becoming a diploid again.
