No, Ai Shizuka is much more reliable than troy - heck, everyone is more reliable for advice than troy, but that's a discussion for another day. Anyways, it looks like a lot of cities either
1)
don't have food resources: Cities 2, 5, and 6
This will make it very hard to let the city grow without building a bunch of farms, and even then it will still be difficult for it to grow. A good rule of thumb is to have at least one food resource in a new city (unless it's just to grab a resource, in which case grab the resource then switch it to just build wealth/research).
or
2)
just there to take up space: Cities 5 and 6
No point in building either of these other than to grab the land. I guess you could just set them to build wealth/research, but other than that they're pretty useless. Also, you should move your capital to St. Petersburg or City 1 to help reduce maintenance.

What to do with: Cities 2, 5, and 6
I would move City 6 to one tile SW of the Rice, so you can hook the rice and the stone. Yeah, I know half desert tiles isn't great, but it's better than all tundra with no resources besides whale. City 5 should stay where it is, but it should be a very low priority city. You can just set it to build wealth/research once it can't grow anymore (and by then, since it has no resources, it won't be the best city ever). For City 2, it will have a hard time growing like 5, but with the Horse and Wine, it shoudn't be that bad. Just don't expect it to have a very big population.

Build Priority: 4 or 1, 6, 3, 2, 5.
4 and 1 are pretty evened out, there about equal distance and equally good. 6 can hook you up with stone to help with wonder building, and 3 gets you horses for military purposes. 2 is basically just 5 with horse and wine (and its coastal), so it gets the nod over 5.
How to Use the Cities

How you should specialize: all your cities
Moscow looks like a GP farm, 1 could possibly be another GP farm if you need it, and I can't really tell for the others, because I can't see the individual tiles.
Hope this helped! Remember to move your capital to St. Petersburg (1 and 4 could also work, but St. Petersburg would help the most maintenance wise) once you start settling the other cities.
