Hate to sound stupid, but what are these tiny vents for?

With a Hip roof there is very little ventilation at the top. Usually just at the soffitt areas. BAD DESIGN! After realizing that there is a problem they will usually install those style vents to save their ass.

Those lower ones look like kitchen and bath

The larger upper ones are off ridge vents for ventilating the attic, the smaller lower ones - as David and Wayne stated.

That said, based on what is shown in your photo, that roof does not have adequate upper venting to meet the requirements for ventilation of the attic. How many more of those upper off ridge vents are there? What is the square footage of the attic?
