Question About Russia Stamps 1920's

I don't know anything about stamps but recently came into some stamp albums and am trying to find out about a few of them. These were all together in an envelope in the Russia section. A few have dates on them but I have no idea about the rest. Are they all from Russia and from around the 1920's? Any idea of value? Thanks

I spent about a half hour looking for the two taller ones in the first row but I have had no luck finding them. Either I just missed them or they're a type of revenue or possibly a local issue.
