I just noticed the rightmost guy in the second picture here appeared in a military show earlier this year! He is one of the first J-15 pilots. Link here, at around 13:40:
I think he is the new commander of the carrier wing replacing Dai ming meng who is now the chief of all carrier program

It was a dream from childhood to fly into the blue sky for Dai Mingmeng, who became the first Chinese pilot to successfully land on and take off from China's first aircraft carrier, in a J-15 fighter jet in 2012.
Two months after China commissioned the Liaoning carrier in September 2012, Dai landed a J-15 on the carrier's flight deck, the first Chinese pilot to achieve the feat. And he then began training carrier-based fighter jet commanders and drillmasters.
On December 18, Dai was selected as one of the 100 representatives who made great contributions to China's reform and opening-up.
