You can try disputing the accounts in the hope that the creditor won't verify. However, you have no basis to remove true and accurate (albeit negative) information from your credit report, and most negative items can be reported for 7 years.
There is no way to remove them sooner.

I agree with the others. I also would ask this - why does it matter to you that they are there? Any future credit and lending decisions will be based not only on your credit score, but also on your income and ability to repay. If your incom is low and you were unable to pay previous debts it sounds as though incurring new debts may not be the best option for you to move forward.
