What the languages look like to me (top-bottom, left-right): Swedish, Norwegian, German, Finnish, English, French, Polish.

I know English and French, am learning German, and have seen a TON of Finnish and Polish stuff (mostly music lyrics). The other 2 are clearly northern Germanic languages, but it’s hard to tell which (the first one can’t be Danish because they usually use ø instead of ö, and I don’t think Danish usually uses å, but the second one also looks like Swedish to me… so it’s a shot in the dark).
