I've done a bit of research on the trikes pictured. I've found out that the 1st one on the left, is a Hettrick American probably of 1940's vintage.The Hettrick has it's original rear wheel hubcaps and a Troxel saddle. The only thing I see missing are the grips.
The second one from left. Red, white, and blue is a Colson which I believe to be from the 40's as well is missing one pedal and both grips.
The 3rd trike from left in the back row... red Murray manufactured Steelcraft. I believe this trike is from the 20's possibly earlier. It is missing grips, seat, and a pedal.
Fourth in the back is a vintage similar to the Steelcraft 1920's maybe earlier. I don't know the make or model. There are no distinguishable markings. It has both pedals and a seat. Missing both rear wheels. Maybe Gendron, Colson?
Clockwise coming to the front of the picture on the right, I believe a 1950's basic trike by Murray. Maybe Mercury?? IF such a thing exists? Complete except for grips and rubber. The trike beside it looks to be an exact copy missing wheels, bars, fender,etc...
The small pile of parts in the very front of the picture is unknown to me. Basically just a solid frame. Maybe another 50's Murray? It has Clipper Puncture Proof tires and some interesting rims that have more spokes than normal? There is one dome shaped metal hubcap.
I will post more pics in the future w/ measurement info.
