The answer to the question of which column corresponds to which button (selections) is that it depends on how the vending machine is programmed. Each button can be programmed to correspond to any of the 12 columns. This allows you to have multiple columns of Coke or Pepsi for instance and have all two or three columns linked to the one button.
Your best bet on learning how to program the machine properly is to get a manual. If you do not have a manual but still want to operate it 'as is', you can test by placing different products in each of the columns. Push the selections and see what comes out from each button.
As to refilling machine, it also depends on whether you have it set up for cans or bottles. If it is set for bottles, then the tops of the bottles always point to the outside of the machine. Thus the front row tops point to the front of the machine and the back row tops point to the rear of the machine. If set for cans, it won't matter which end is which although the machines usually have a diagram on the door with recommendations as to the best way to 'set' the cans.

A vending machine costs anywhere from $100 (very compact, 4-8 small selections) to $20,000 (large, varied, many selections, refrigerated). It depends what vending machines.
