First of all, you asked for scarring and hole or not, that's scarring on the facade. Second, the damage in photos #3 to #5 is much less severe (the limestone is removed, so it is not the case that there is no damage) because it was the lightweight outer part of the wing that struck this area. The majority of the wing, including the heavy fuel tanks, entered the building, producing the hole you see. That hole spans between column 8 and 14 (whereas the hole for the right wing spans between column 14 and 19). So yes, the wing penetrated the building and the visible evidence of penetration is there to see in the photos.
When you look at all the evidence together, overwhelming evidence really, it becomes rather silly to focus on things like this without keeping in mind the overall facts. For instance, if you look at the impact damage of AA11 and UA175 at the World Trade Center, you will similarly see that the impact holes and removed cladding do not correspond to the entire length of the wings and height of the tail. It's rather similar, the heavier more massive parts of the plane penetrate, the lighter parts damage the stationary building less. And the structure of the building played an important role in determining the shape of the holes you see, such as the second floor slab which was at a separate plane from the impacting wing (see ASCE's Pentagon Building Performance Study for a discussion).
I find anomalies interesting too, and chaotic events (like a plane crash) tend to produce their own anomalies. Like it is kind of amazing that all the falling steel from the collapsing towers managed to miss the Sphere sculpture in the WTC plaza; how on earth was it not flattened? That's a pretty amazing anomaly. But anomalies usually have good physical explanations once the facts are accurately understood. What I found about 9/11 truthers is that these "anomalies", such as those pertaining to the Pentagon crash, are not anomalies at all but simply represent misconstruals of the facts. Loose Change is filled with such inaccuracies.
