8 ounces of butter (1/2 pound) is one cup.
It largely depends on the size of your cup, you really would be better off weighing the items.

A fifth of a cup is 1.6 fluid ounces
That is 2 oz.

0.62 cup
There are 8 fluid ounces in 1 cup, so 1 oz = 1/8 cup = 0.125 cup.
I liquid measure, yes. One cup = 8 ozs.
Really up to you. I would say around 3 ozs would be enough, but you can put more or less according to taste. Cup is usually around 4 ozs.
2 oz is equivalent to 1/4 cup or 4 tablespoons.
