From the Lippisch DM-1/P.13 we got the XF-92, F-102, F-106, and B-58.
Not directly, as the DM-1 was a rather flawed design. The very basic
idea of a "delta" wing was his first, but it would not have been any
kind of stretch for others to do it, and the original work on the XF-92
(especially in its original form) owes very little to Lippisch.
