According to Mr. Yeager's history class, 7 of the 9 titan shifters abilities were under the control of Marley. (R.I.P. Bertolt)  We don't know yet all of them, but it's very likely the Quad is a shifter, Erwin can't be wrong :), so there's still one unidentified left.

About the 2 titans Marley didn't get, we all know which was the first one, but for the second, I think it was the Attack titan (the Erens and the Yeagers titan). We know Kruger managed to fake his blood test and become part of Marley army, plus his colleagues seemed pretty surprised to see him transformed. Moreover, Kruger told Grisha that "this titan, no matter the age, has always moved ahead, seeking freedom" (ingeniously tying this titan with the Survey Corps and the wings of freedom, awesome!!!) It may seem "in character" that the holders of this titan wouldn't have let it fall under the control of anyone, no?
