What does the green indicator really mean? Does it mean the locking mechanism is off? I understand that the door would not open in mid-air due to pressure diff. but will it open when someone pushes the door?
Apparently there is a gap at the bottom of the door. Does that mean that the door has 'partially failed'? I.e.: The lower bit of the door has actually left the frame?

Let's put things in perspective : differential pressure will push the door to its cushions, even if the locking mechanism is off.
Considering that the door dimensions are some 84 by 50 inches and considering that the differential pressure is around 8 psi, 84 x 50 x 8 = 33,600 lbs ; That's the force applied on the door... some 15 tons... if you push, you add your weight to that force...
There is always a gap at the bottom of the door to allow it to get into the fuselage before it is forced to "unfold" into its seat. That gap is, for cosmetic reasons, covered by souple plastic.
There are ruber-compound seals, though, and one is probably leaking, making a sort of shuddering whistling noise, which can be rather loud. The cushions and blankets have been used by the cabin crew to partly mask that noise.
Much ado about nothing, or as we say in French :" beaucoup de bruit pour rien."

When you close an Airbus door, the final movement is that the whole door lowers about 2 cm, and the seal at the bottom of the dor pushes against the door sill. Sometimes there is rubbish left here, maybe a swizzle stick or a stone from a passengers shoe. Then there can be a deformation of the seal, and some air can leak out of the cabin. As the hole is usually very small, the air will whistle as it leaves, and it can get very noisy. Pushing blankets up against the door can help. It is quite a common occurence.

I can assure you. The Door didn't come open. The Lower door seal blew out and that can happen if moisture freezes on the door sill or there's foreign object damage to the lower door seal. Had that door come open the seats ar the right of that picture would have departed the airplane and NO amount of tape would have covered it up. Trust me on this.
The passengers were in no danger. The repair once parts were available would be 6-12 hours
