Need help to ID some tools

[DPNM]

I recently purchased an airbrush lot. Besides the airbrushes and related parts for them there were some X-Acto handles, quite a few  X-Acto #11 blades, some T-pins and the 3 tools in front of the box. I have no idea what these tools might be for. The one on the left and on the right look to have been made well. The one in the center looks to be home-made. They seem to be made from aluminum. I doubt they're model related. They may or may not be auto related. 

I know there is a diverse group on the forum. Maybe someone here might know what these would/could be used for. Any help will be appreciated.

The one on the left looks like a light weight spanner wrench , the middle could be the same , only home made for a different size , the one on the right is what you'd see if a 3 fingered robot flipped you off . Honest !
