Need these 3 parts

I'm afraid I don't recognize the parts in your photos. The first two photos look like they're showing a kind of lock or latch, but I cannot determine what it is. The second photo shows what looks like a bumper, maybe. Finally, the last two photos show what looks to be door glazing.

Can you briefly describe the function of each part? Can you also remove each part from the door and show me a photo of them by themselves? Knowing their dimensions would also be a huge help. For the glazing, we'd need a clear picture of its end profile.
