LoL I don't see anything serious to the proportions you implied. Nothing a simple band face pull and towel tuck cannot fix if they have tight chest and C1-7 issues.
Shoulder flexion and abduction are normal default positions for an average guy, wouldn't you agree? Significant? Not really, they all were in the safe zones, less than 45 degrees and elbows in front of shoulders. Maybe it's good for bigger biceps and lats? LoL Except for the innermost guy, who had his elbow way front and a bit hunched over, they seemed to have a natural spine. Nothing serious to complain about.
Plus people come in all different length and proportions, long short torso, humerus etc. As long as one can make necessary adjustments and have a proper sitting posture, with or without lumber support, I believe that would not seriously impede operations.
They are not sedentary office workers. They have morning drills, and most likely an onboard gym.
Regardless, I agree sitting posture is important.
No, I wouldn't agree. The most ergonomic position is "neutral posture", where there is almost no shoulder flexion or abduction, and no back flexion. All three are present to varying degrees in all three personnel in this photo. The main screen is positioned such that its perpendicular aligns with the eyes, with the person eyes looking slightly downward. Neither of these are true for any of the three personnel. The seat is positioned so that the seat back contacts the spine at multiple points and allows the person to sit in neutral posture or even slightly reclined, not sitting forward with no back support, as in this photo. Will poor ergonomics kill these people? No, of course not. The point is crew comfort and crew effectiveness. Do it right instead of making excuses for why it should be ok that you did it wrong.

LOL by your own description your middle guy is already leaning forward yet even in his current position he will not be able to touch the screen, nor would a horizontally-held arm touch the middle of the screen. Nor is he sitting back in his chair, to speak nothing of a slight recline.

As for 17-18 degree angle of the monitor, that is in reference to a point BELOW the eyes of the operator, NOT above:

So see the middle guy has 17 degree viewing Forget about the monitor above it is secondary monitor in the old days it was reserved for annunciation panel with light and buzz(see the rectangular thing) that warn you if anything goes wrong The main console is the bottom one

How many Type 052 ships are under construction and/or testing?

Dalian ---
2 under construction
1 fitting in the dock (looks finished but just moored there)
1 in and out for sea trials (this might be delivered soon)
1 recently delivered

Jiangnan
4 in the water fitting, meaning four in the fitting pool
? in the sheds under construction. Can't be clear if they are stretched 052D or 055. Possibly two under construction?
