exact change

"I paid for pizza $15 in exact change." If I paid $20 for a pizza that costs 15, could I say that I got $5 back in exact change meaning that I was not shortchanged?

I suppose you could but it really doesn't sound very natural; "I got $5.00 change" sounds better.
"Exact change" usually refers to a payment of the specific amount required. Many urban bus lines in the U.S. accept "exact change only" in their fare machines, meaning that the box will accept only coins and the driver will not change paper bills.

Ostap, note that we say fifteen dollars but write $15.

If I were paying for goods to the cashier in a small store and wanted to ask if he would accept a 50-dollar bill, would it be OK to ask "Do you change a 50-dollar bill?"

I'd be more likely to ask "can you change a 50?" "Dollar bill" is implied.

We use "exact change" as discussed above - If what I purchase is $17.52, I pay with a ten, a five, two ones, two quarters, and two pennies. (Although the 52 cents could be another combination, and I could give the $17 as three fives and two ones, or even 17 ones, etc.) The point is that I give the cashier the exact amount of the sale.

If I were a cashier, could I ask a cusomer if he was done putting groceries on the counter and wanted me start counting "Shall I coun the sale?"?

"Shall I start ringing it up?"

Actually, I'd be quite surprised by that question. If I've put it on the counter, then that's exactly what I expect the cashier to do. To ask my permission to start is unexpected. Just start scanning and get on with it, I would think.
