I would say that the first batch ALL have too little head space. People in these types of 'conventional' shots need a bit of "air" above their heads, especially when there is ample chest and torso shown below; it's one thing if the pose is a tight headshot, or even a bust shot, but on a half-body shot, having three or four millimeters above the top of the head feels visually "off". In a very studied, formal, classical Portrait (capital P)...allowing extra head space is a fairly standard, classical convention. In casual, informal, fun, free-wheeling 21st century snaps, one still needs at least "some" head space on shots like these.
