Say the horizontal tube is a vacuum in which fluid is running through, and the vertical tube down the middle has average air inside (w/gravity). Is this possible? What would happen? (▼ see diagram below ▼)

Over time, the vacuum would equalize throughout the apparatus, although through long distances, gravity can alter the pressure and density of air.
I'm not quite sure what you mean by "average air".
Is the "liquid" capable of descending down into the side tube?

You may look up the Venturi Effect, in which the pressure in a side pipe at a point of restriction actually decreases.
