My 22 year old twins live with us. they both filed there taxes and claimed themselves as dependents. can i also claim them?

No.  If they filed their tax returns indicating that they cannot be claimed as a dependent on someone else's return, then you cannot claim them as dependents on your tax return.

If they incorrectly indicated that they were not dependents and should be a dependent, then they need to file an amended tax return and change their dependency status.  If that is the case and they could be claimed as dependents on your tax return, then you will have to print and mail your tax return claiming them as dependents.  You cannot e-file your return since a tax return has already been accepted by the IRS with their Social Security numbers on a tax return.
