You’re describing the younger one on the right of the pic. That’s Festa.

I’m asking about the one on the left, blue tracksuit, white stripe, facing Giallanzo.

The caption on that surveillance picture describes these two as a Colombo capo and an associate. Thanks to Ralphie’s insight the one in the middle with the brown tracksuit could be Catapano, who was ID as a captain in 2010. There are plenty of pictures of him online and although he’s giving his back to the camera he could easily be him given his hairline and head shape.

The other unknown fellow looks younger. Roughly Giallanzo’s age I’d say.
