there are various type of barometers viz. mercury barometer, aneroid barometer, precission aneroid barometer. Barometer thus calculate the pressure exerted over a unit area by the column of air over that area.

Yes, both devices measure air pressure. The difference is the mercury barometer is filled with a liquid which could spill (and mercury is toxic) while the aneroid barometer contains no liquid.

What is the difference between how air pressure is indicated in a mercury barometer and an aneroid barometer?

Usually no difference at all. They can both move a pointer around a circular scale. The scale can be calibrated in both Inches of Mercury (InHg) or Millbars (Mb). An aneroid system can lend itself more easily to a digital display.
