OK,
If you have added the same qty discount to all of these products and these are the ONLY qty discounts in your cart...
DO NOT USE THIS if you have other items with qty discounts
First place shop down for maint then using phpmyadmin, make a proper backup

Then to check, use phpmyadmin and export only the products_discount_quantity table not compressed
Open this exported table in an editor and assuming that you have actually added them all identically, you will see something like this - -
Where the red highlighted value is discount_qty
Code:
(1, 8, 3, '10.0000'),
Now the number/levels of discounts for example if you have "5" levels you will need to run this sql 5 times adjusting for the discount_qty values you have and the desired price where highlighted
Code:
UPDATE products_discount_quantity SET discount_price = 10.0000 WHERE discount_qty = value;
It should look like this where the discount qty is 3 and the desired price is 10.0000
Code:
UPDATE products_discount_quantity SET discount_price = 10.0000 WHERE discount_qty = 3;
I suggest you run one and view the result before continuing
If all goes bad you have a backup
