That looks like a young Stan Howe on the right.
I see Mark & Sparkle Farkle, but where's their uncle Ferd Burphell ?
Second from the left is Fannie Farkel, who set a record as being America's fastest stenographer for 1928 & 1929.
Fannie's sister, already identified as Sparkle, went on to become J. Edgar Hoover's seamstress.
The two boys on the right, Hemphill & Buhl, went into business together and made a fortune in the tapioca business. Sadly, they were ruined financially in the great tapioca panic of 1939. They later had minor success as the comedy team of Hemphill & Buhl.
The strapping young lad on the left was Narse. Narse was lost in the Battle of the Bulge. Mind you, he wasn't killed or wounded, just kind of misplaced. Not much more was known of him.

Of course the sight gag was that all of Fred and Fannie's kids had red hair and freckles, just like "trusted neighbor" Ferd Berfil.
Here's a couple of minutes of fun with the Farkel Family:
