Definietely, both types were used by a lot of units, and many of those operated in the East in 1945.
Elements of JG 3, JG 11, JG 52, JG 53, JG 51, JG 77 had 109Ks and operated in the Eastern Front. Because they almost always operated a mix of G-14, G-14/AS, G-10 and K-4, its difficult to tell the precise number at the moment.
As for D-9, I recall seeing a German newsreel in 1945 showing them operating in Prussia, or so the commentary said.
