    Using 281 pb{sup -1} of data collected with the CLEO-c detector, we report on first observations and measurements of Cabibbo-suppressed decays of D mesons in the following six decay modes: {pi}{sup +}{pi}{sup -}{pi}{sup 0}{pi}{sup 0}, {pi}{sup +}{pi}{sup +}{pi}{sup -}{pi}{sup -}{pi}{sup 0}, {pi}{sup +}{pi}{sup 0}{pi}{sup 0}, {pi}{sup +}{pi}{sup +}{pi}{sup -}{pi}{sup 0}, {eta}{pi}{sup 0}, and {omega}{pi}{sup +}{pi}{sup -}. Improved branching fraction measurements in eight other multipion decay modes are also presented. The measured D{yields}{pi}{pi} rates allow us to extract the ratio of isospin amplitudes A({delta}I=3/2)/A({delta}I=1/2)=0.420{+-}0.014(stat){+-}0.016(syst) and the strong phase shift of {delta}{sub I}=(86.4{+-}2.8{+-}3.3) deg., which is quite large and now more precisely determined.
