In your first pic, the one the left looks like an old whiskey. What's the embossing on it say? The bottle on the right is a drug store bottle, probably from the 30's. It looks like it has writing on it too.Usually these bottles would sit on their edge on a shelf so you could read what it contained... The middle bottle looks like a newer wine bottle. A way to tell how old a molded bottle is, look at the seam below the lip. the closer to the shoulder the seam starts, the older the bottle. There are other factors, but this will give you a starting point for bottle age.
