The first is what we call a ring seal here, probably a wine/champagne or beer but they where a generic bottle that had everything from vinagar to tomato sauce in them as well.
Second I've no idea [] . last one I'd say medicene too. I agree with Gunther as to the age of them, Ring seals can date from the 1840's or older up to the late 1920s but yours looks around the 1900 mark.
