Pat yourself on the back - you got the CD numbers right.
L to R -
CD 121, Am Tel & Tel - I think yours is a light bluish aqua. These are commonly used on local and long-distance lines (long distance for their time period, which would have been between two nearby cities), maybe late 1890s-1920s. Not a great deal of value unless you have an unusual variant, perhaps a dollar or so.
Deenodean - The eBay link.... um, I have some reservations about that cornflower color. I don't know for certain, but it resembles irradiated insulators I've seen, and the fact that the same seller's listed purple Kerr jars doesn't inspire confidence.
CD 102 Brookfield - this "pony" style turns up on local phone lines, around 1903-1920. Brookfield produced many of these, so they're quite common, perhaps a dollar or so.
CD 133 Brookfield - this is the oldest and probably most interesting of the lot. The style originated with telegraph lines but later versions tended to be used on police/fire alarm lines, but also wouldn't be out of place on a phone line. Brookfield went to skirt embossing in the mid to late 1890s so this is probably late 1880s-early 1890s. Still, it's not terribly rare or unusual, so about two dollars.
