Answers.Text: Indeed, they do have "Lego" on the inside of the hollow studs. The hollow studs, and the slightly unusual lower attachment confused me. Thank you @alex

  LEGO logo is visible inside hollow studs on genuine parts. While it is hard to identify if pictured items are genuine LEGO parts, such elements have been produced as LEGO:
  
  [Window 1 x 6 x 3 Panorama with Glass](https://www.bricklink.com/v2/catalog/catalogitem.page?P=604c01#T=C)
  
  [![enter image description here](https://i.sstatic.net/hj17s.png)](https://i.sstatic.net/hj17s.png)
  
  Window 1 x 3 x 2 could be either one of [these](https://www.bricklink.com/v2/search.page?q=31b*#T=A).

  Window 1 x 1 x 2 could be in two versions: [with integrated glass (single piece)](https://www.bricklink.com/v2/catalog/catalogitem.page?P=29bc01#T=C) or [with glass that can be attached (two pieces together)](https://www.bricklink.com/v2/catalog/catalogitem.page?P=29c01#T=C).
