Hard to tell without the reverse.
The $1 is an F- (book $10)
The $2 is an F/VF (about $30)
The $5 is an F/VF (about $30)
The $20 is a G, although with that many tears, I wouldn't buy it.
And the $10 is an EF. It cannot be an AU with that edge on the top-right. But again, it depends if the reverse is just as sharp.
If you want to get maximum value, put 'em on eBay when the USD is relatively strong. I tend to keep my bills until I get better ones. Speaking of which, I will soon take out a batch to sell.
