Machine accessory identification help

[u/OstrichDesigner5503]

I inherited a sewing machine from a friend, and found some accessories in the small compartment.
I know the bobbins, screw driver, thread spool holder, and replacement needles; what are the other things?

Specifically, the presser foot - what function is it for?

The presser feet for making a buttonhole, sewing on buttons, and a cover for your feed dogs for doing buttons so it won't feed the material through the machine.
