When we say "last one" or "first one" it is assumed that the listener knows the context and therefore what the "one" refers to. When we use "first" or "last" alone, it is generally as an adjective to modify the exact noun that was "first" or "last".
Here's an example:
Dave: "Did you take the last cookie?"
Steve: "Yes, I ate the last one. But didn't you eat the first one? So it seems fair to me."
