It is not impossible for Russians to get a B2 Tourist Visa but with the situation it certainly is not going to be easy. I assume she could apply at the Consulate in Georgia. Loads of Russians are obviously desperate to get out and with no immediate plans to return, presumably you can see that in Georgia.
To get to Poland they would need Schenegen Visa's. I have seen others discuss this on VJ, certainly not impossible.
To visit other Countries you need a Visa if required, some countries are visa free for Russians.
