Franco Bollo Postale. These stamps were from independent Italian states before the unification of Italy through the 1860s and 70s (Italy actually fought three wars of independence). These are specifically fro m Roman States, which started issuing their own stamps in 1852, and discontinued in 1870, when they joined the unified Italy and started using Italian stamps. The problem? There are A LOT of forgeries of Roman States stamps out there. I bet these are forgeries but we'll see.

In 1865, The United States issued newspaper stamps that could be used to bulk mail newspapers and periodicals within the United States. This was discontinued in 1898.

This stamp is from the Russian Army of the Northwest under General Yudenich. After the overthrow of the Czar in 1917, General Yudenich fled with 17,000 troops to the northwest, where he joined a "Provisional All-Russian Government" to oppose the Bolsheviks. By 1919, he'd pushed the Bolsheviks out, but with no outside support, his army could not sustain, and it disbanded in 1920. General Yudenich settled in exile in France in 1933. This stamp has an inverted overprint, written in Cyrillic.
