Definitions are surprisingly varied. I see these words as being something to be cautious about.

For me:

couple(formal) = 2

couple(informal) = 2-3

few = 3-5

half-dozen = 6

[gap]

ten-or-so = 9-11

dozen(formal) = 12

dozen-ish(informal) = 11-14

And don't get me started on "this Friday" vs "next Friday"...
