A couple of potential ones, both from the red bus pic.
The woman near the bus stop sign on the far left of the RB pic could be on the far right of the WW crowd pic. Dark clothing, big collar. Tenuous at best tbh.
The other is the asian woman from the far left of the red bus pic. Next to the tall guy, kind of ducking behind him. Not much to go on, but she is short, asian appearance (could be lighting), fluffy white collar.
I think that there is a reasonable chance that the other WW pic was potentially taken using selfie stick guys phone. She is chatting with the vendor/taking a photo(?)/buying the stuffed toy that they are then both posing with in the group shot. He is checking email/texts. I'd estimate (very) roughly 6-8ft away. Phone potentially angled towards the vertical if drizzly/very light rain.
Actually, forget that. Who I had as a "vendor" (if vendor he doesn't have much stock) is most likely red hat, same jacket/jumper, neck covered. He is posing for a photo with the stuffed animal, selfie stick to hand. Not sure which order they were taken, but also not too far apart as same people checking map/direction board. Probably group first, then she took phone from selfie stick to take solo pic.
