I don’t think he is Yamamoto. This guy appears to have a ponytail, and if the dark mark on his cheek is glasses, it is a wider bow, not the narrow wire bows that Yamamoto has. The photo by the ambulance, where the rescue workers are patting somebody on the back (which seems like it would be the “distraught” Yamamoto who would need the extra comforting pat on the back) shows him wearing blue swim trunks (as he was later described at the Honolulu airport) and a sweatshirt, which he was probably wearing over the top of the shirt he was seen leaving the Honolulu airport in at about 7pm. Also, I think Yamamoto is heavier-set than this guy.
That guy could be Jacob Key, which would make sense since he’s close to Rosa Key. But like you say, the shirt doesn’t seem white; it seems more brown. The person sitting across the aisle from Fuddy was wearing a brown short-sleeved shirt which would make it seem like it was Yamamoto. But I don’t think it is Yamamoto because it doesn’t fit what Yamamoto was wearing in the other photo or what he is described as wearing at the Honolulu airport.
I think it has to be the 70-year-old guy. Seems well-preserved, if so, but then when I look at the photo of the woman on the stretcher all wrapped up she doesn’t look 74 to me either.

Certainly it's far from certain that the man in the image has a ponytail. And it's conceivable that Yamamoto could have been wearing eyeglasses with frames different than the eyeglasses he was wearing in his file photo from a couple of years ago. But that file photo tells us that Yamamoto has some visual impairment mitigated by eyeglasses; so does the man in the picture, or else he wouldn't be wearing glasses in the emergency.

Haven't seen that photo. But if you say Yamamoto was wearing a sweatshirt and swim trunks at 7 p.m. that day, it certainly doesn't rule out the possibility that he had been given the sweatshirt to wear over the gray (?) shirt he may have been wearing earlier in the day in the image at # 45.
That guy could be Jacob Key.
No way! Key is Caucasian and has sandy brown hair. (Saw him on a video standing next to his wife, Rosa, who is the heavy-set woman of Asian heritage who was wearing the white shirt with the gray stripes in the water. Rosa was being interviewed about the incident.)
The guy we're talking about in the image is of Asian background and he's NOT the pilot Kawasaki. And he's not over 70 years old, or at least doesn't appear to be. By a process of elimination - assuming that the passenger and pilot identifications are correct - Keith Yamamoto is most likely the man in the image, second person from the right. (The first person from the right is surely Rosa Key.)
