The relationship is called a surjection or a surjective function.
It is a mapping which assigns one or more outputs to each set of one or more inputs. A relationship need not be a function.
Is called "function".
A one-to-one or injective function.
It's depends on the line spacing. At 6 lines per inch, which is quite common for text-mode computer output, you get exactly 48 lines (with leaving a space for margins!). I believe typewriter output would be similar to this.
This is true. Furthermore, functions can be broken down into one-to-one (each input provides a different output), and onto (all of Y is used when f(x) = y).

There need not be any relationship.
A Function
A function is any relationship between inputs and outputs in which each input leads to exactly one output. It is possible for a function to have more than one input that yields the same output.
