From looking at pictures of a 2006 Odyssey 505, I cannot think of any usable awning that will not cover neither the window in front nor behind the door.
Also the awning light appears to be over the middle of the three (kitchen) windows. The rear bedroom window is too close to the door for any awning not to at least partly cover the window. To allow both the awning light to be usable and all windows to be openable then you may have to go for a full awning as the gaps between the windows do not look large enough for the slope on a standard porch awning.
Sorry if this is not the answer you were hoping for.
