In your first photograph I spot what seems to be Panel 1x4x5 Wall with Window in dark bluish gray:

LEGO doesn't have any elements that have such geometry and offer connections for both pins and axles. The closest you can get from LEGO right now is Plate, Modified 1 x 2 with Pin Hole on Bottom
And Technic, Brick 1 x 2 with Holes if you need to attach two pins/axles.
