Nice collection! Looks like all the planes have the cutting blades with them.
If you could stand the planes bottom up so the molding profile can be seen, that would be helpful. Sight down the molded profile and take a picture. The profile will tell what the planes were used for.
Could be they were used for raised panels and frames, table top edging, trim moldings etc...It would also help if you numbered each plane with a piece of tape and a marker to identify which is which.
