Hand Tool ID - Craigslist Mixed Lot

[Off-Street Parking]

Here is a generic mixed lot of tools I found on Craigslist.
It's the usual deal, several separate "clean out the house" lots posted from a seller and priced as sets.
But the question is... What are they?
(The grass shears are a given. )

The picture is a bit small, but one on the bottom left is for cleaning ring grooves on pistons. The bottom right might be the same, but I can't see the head on it. I think there is a water separator or filter in the middle. Not sure on the other two or the box.
