Sorry - I'm far from expert in Russian. But hopefully I can answer some of your questions. I've had a look at some google images for your words Самса - Samosa maybe? Сочник - I'm not sure- as it would depend on the filling. Is it perhaps like a pastie? ватрушка - I've never seen anything like that. Perhaps if we don't ever make it or eat it, there is no translation. сырный пирог - Looking at the google images, there seem to be a few dishes. 'Cheese cake' is always sweet. Although it doesn't have cheese in it, it does usually have cream cheese. There seemed to be a few savory dishes in there - those looked more like quiche. Булочка - looks more like a sweet bun. Булка - bread roll? Плюшка - possibly cinnamon roll, if it has cinnamon in it. Certainly 'sweet bun' would be more specific, if it doesn't Пирог - possibly strudel? Торт - Torte Тортик - possibly layer cake? I can't see an obvious difference between Тортик and Торт based on the pictures. How are they different? Пироженое - seem to be various things. I saw macarons, tartlets... Perhaps 'pastries', which is a generic term?
