1 looks like a whisk or honey dripper.
2 looks like some sort of item that you can pass a dough (or other soft item) through and adjust the thickness. Maybe for a breadstick or some such? I enlarged the image by clicking on it and you can see the roller and the adjustment knob.
3 looks like some sort of peeler, or maybe a cheese knife?
4 looks like a zester, but to make ribbons or strips instead of tiny pieces. (Chocolate curls?)
