a spine
A sharp projection from the surface of a bone is called a process. Bones can have different types of processes, such as a spinous process, which is a sharp, pointed projection; or a tuberosity, which is a large, rounded projection. Processes serve as attachment points for ligaments and tendons.
A meatus is an opening; therefor, it's a depression, not a projection.
Mastoid process
There are actually two terms that could answer this question depending on the size of the projection/bump. My answer would be "process", however, that is usally associated with large projection/bumps whereas "eminence" is a term associated with small projection/bump. As for ANY bony projection or bump, I do not believe there is umbrella-like term for it.
Re-projection is defined as the process of redoing estimations or forecasts. This is usually based on various trends that are visible.

The bone that makes the posterior point of the elbow is the ulna. The projection at the posterior point of the elbow is called the olecranon process.
The type of projection is called a cylindrical projection. This process involves wrapping the globe's surface around a cylinder to create a flat map.
The same as the slender, pointed projection on the distal end of the radius: the styloid process
