Honestly I'm not sure why you're looking for free info about a person, but if you're trying to find public records or social media profiles, you might want to try using people search engines like Pipl or Spokeo. Just be aware that some of these services might not be entirely free, so use them sparingly.
Not sure about the Russian question, bro. But based on the title, I'm assuming you're looking for ways to find free information about a person? You might want to try reverse image search or social media background check tools like Pipl or BeenVerified (not free, but has a trial).
