The term “a couple” is two. It doesn’t sound as precise as two, but it really is two.

Couple means two, but if it turns out to be one or three, you weren't incorrect. Pair and brace (archaic) both mean exactly two.

“several” is three or four. Two is already covered by "a couple", and and five is covered by “a handful”.

In no way do I associate five with a handful. I've never heard anyone say that. To me, a handful is even more vague than several.

So, I read {puS} as “3-5”.

I read puS as significantly smaller than average. If I've got an army of a five thousand soldiers, and yours is only six hundred soldiers, your soldiers are puS.
