Not sure which screws go where

Hi,

I've disassembled my iPhone 5 to the level where I replace the power/volume flex cable. I am now not sure what screws go in some places, even though I put each set of screws in a different place on the desk by following a video guide. Right now I need to screw the buzz/mute button bracket into place, and I don't know which screw to use.

I found a diagram with numbers for all the screws, but I have no idea how the screws look in relation to those numbers, so it wasn't helpful.

I'd appreciate any help. Thank you.
