I've tried enhancing the photos using the computer with photoshop and blow up 3 add-on. Tried converting the raster image to vector and enlarging it. Even tried with OCR program but none of these ideas worked. In the end I just enlarged each photo and tried to guess what the specific letter was. I do not speak Russian, but N.V.Shavrov's book History of aircraft construction in USSR untill 1938 was a great help in determining the names of the designers. That man also covered the periods between 1938 and 1950 and the third one between 1951 and 1965. Such a shame these books weren't translated in english.
So, here are the results:
Picture 1:
3-view of the B-1 bomber
Picture 2:
Bombers of the state aircraft-building plant No.1 (GAZ No.1), Polikarpov's home base.

Junkers Jug-1,Soviet version of the Junkers K 30 bomber, purchased in small numbers from Junkers in the mid-1920s and regarded as the first effective "modern" long-range bomber in the Soviet inventory.
Tupolev TB-1
I found one picture of the Polikarpov TB 2 and one of the Kolpakov K-1 from 1917 which could have served as basis for his biplane project mentioned in pictures above.
edit: I haven't seen the link in the first post, just gave myself a facepalm. It would have been much more easier if i knew that.
