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?

On the topic of how they do that imagine the cells and their surroundings full of tiny magnets.
1 magnet is not very useful on its own but get another one and now you can attract or repulse each other, add another one and now you can make them change direction, add a lot more and you can make them travel long distances (like magnetic trains), flip them, change their form and even more crazy stuff, but the magnets are still dumb pieces of metal.
Now imagine instead of 2 different magnets, North pole and South pole, you have billions, the proteins and enzymes cells are made of and surrounded with, and you can imagine all the combinations and possibilities doable by just dumb cells
