The subject came up in another thread, but rather than continue to hijack that thread I thought I would address the question here. It's not really about turning, but it is about pens.
A standard ballpoint or rollerball refill consists of 4 components, the ball housing, the ball, the ink and the tube. Some refills also have a cap. I can't find an answer to what the "original fill" is called other than an ink supply.
The tube or tubes that house the refill are called the barrel or barrels. If there is a separate section where the ball housing protrudes, that is called the grip.
The component or sub-assembly which activates the raising or lowering of the refill is called the mechanism. The two most common types are transmissions and click-assemblies. The portion of the click assembly that the user uses to activate the mechanism is called the button.
At the top of the topmost barrel is a decorative ring (sometimes), a pocket clip and the finial. That about does it.
