The top 3 look like they are the old Hong Kong Kai Tak airport, which due to being surrounded by hills required a sharp turn a short distance from the runway and at low altitude to line up with the runway. If that wasn't difficult enough, the airport often had strong, gusting crosswinds. Despite this though the airport didn't have a particularly worse accident rate than any other busy airport, and many of the accidents had absolutly no relation to the airport (and could have happened anywhere). The airport was closed in 1998 and replaced by a new one built on a man made island. The second pictures looks like a normal landing, the plane is still high and the distance from the runway seems shorter than it is due to the zoom. The top one looks worse than it is, with the zoom again being a factor. It's likely that there is a crosswind from the right, so the plane is turned to face into the wind in an attempt to keep lined up with the runway. It will probably land fairly well, if a little rough, or at worst go around. The 3rd though is a bit hairy, since it looks like the wing tip or engine might have, or be about to, hit the ground. Again though, nothing too terrible. The planes in the 4th and 6th pictures must have overshot the runway. It could be on landing, or it could be due to a fault during or shortly after take off, causing the take off to be aborted, but without enough runway left to stop. The bottom photo though looks like it's come down short of the runway. No idea what's caused that, although 2 odd signs are the damage to the underside (although that could have been sustained during the crash), and the rudder seeming hard over to the left (particularly interesting since it's a 737, and they have suffered a number of crashes due to un-commanded rudder movements). Finally, the 5th picture looks like a perfectly normal take-off.
P.S, here is a little video I took of a rarther interesting landing in a fairly stong and gusty 90deg crosswind:
