Here are the years that I believe are correct based on my research and knowledge of Russian currency. The currencies before 1924 are particularly complicated and nuanced. If it becomes necessary, I can provide which notes need to be in each currency for swift implementation.
Imperial Rouble, Until 1922
First Soviet Rouble, 1917-1922
Second Soviet Rouble “Gold Rouble”, 1922-1924 (1/10 Chervonets)
Third Soviet Rouble, 1923-1924 (worth 1 000 000 First Soviet Roubles)
Fourth Soviet Rouble, 1924-1947 (worth 50 000 Third Soviet Roubles and 1 Gold Rouble)
Fifth Soviet Rouble, 1947-1960 (worth 10 Foruth Soviet Roubles, coins unchanged)
Sixth Soviet Rouble, 1961-1991/1992/1993 (depending on country) (worth 10 Fifth Soviet Roubles, low-denomination coins unchanged)
First Russian Rouble, 1992-1997 (at par with Seventh Soviet Rouble)
Second Russian Rouble, 1998-Present (worth 1 000 First Russian Roubles)

There are several differences between this list and the one I provided. We won't use names like “First” or “Imperial” in the final currencies, so they are only there for now to help see the progression. The first difference is your “First Soviet Rouble”. The notes issued between 1917 and 1922 were the same currency as the earlier issues and the country was still called Russia, so there's no need for a new currency starting in 1917. You then have “Second Soviet Rouble 'Gold Rouble'”. In fact, this covers two distinct ruble, one introduced in 1922 and the other in 1923. These are the two I described in my earlier post, neither of which were called the "Gold Ruble". The Chervonets was a distinct currency (nominally backed by gold) when first issued in 1922. Your “Third Ruble” is correct but your “Fourth Ruble” is in fact the “Gold Ruble” (see here for an example) which was set at 1/10 of a Chervonets. After that, we agree.
When we get the countries set up correctly, we'll need the following:
Russia, Until 1922
1st Ruble, Until 1922
2nd Ruble, 1922-1923 (worth 10,000 1st Ruble)
Chervonets, 1922-1924 (only notes dated 1922)
3rd Ruble, 1923 (worth 100 2nd Ruble)
USSR, 1923-1992
3rd Ruble, 1923-1924 (continuation of the Russian currency)
4th Ruble, 1924-1947 ("Gold Ruble" worth 50,000 3rd Ruble and 1/10 chervonets)
5th Ruble, 1947-1961 (worth 10 4th Ruble, coins unchanged)
6th Ruble, 1961-1992 (worth 10 5th Ruble, low-denomination coins unchanged)
Russia, 1992-
6th Ruble, 1992-1998 (continuation of the Soviet currency)
7th Ruble, Since 1998 (worth 1000 6th Ruble)
If needed, I can provide a full list of the coins and notes that will fit into each currency but it would be easier simply to set them up, move the pieces to the right place, then let everyone check for errors. One apparent anomaly are the coins produced by the RSFSR before the creation of the USSR, which were issued in 1924 as part of the 4th ruble. We currently have them listed under the USSR based on when they were issued rather than when they were produced. However, as long as a comment explaining this is given, we can leave them as they are.
