我在俄罗斯长大了。 I grew up in Russia  (I think this is what you mean, right?)

现在我住在中国。  Now I live in China

 中国是一个很好的国家。 China is a very good country

他们都很好。 They are (all)very  good.

Great start! Keep working hard!!

我的中国!

在住 is wrong, there is no such expression, whereas
住在 these 2 characters often use together, which means "live"
That's why I switched their positions in the sentence.

我 (I / I am) 先 (first / before) 住在 (lived in) 俄罗斯。我 (I / I am) 現在 (now) 住在 (living in) 中国。
This is what u meant in your original sentence.

It's more concise to express it this way, 我 從 (from a place / a time; come from / start from) 俄罗斯 移居 (moved / immigrated) 中国
This meant: I moved from Russia to China
