A meterological type of barometer uses a column of mercury that is supported by atmosperic pressure. The height of this column varies with the atmospheric pressure and was at one time measured off in inches in the range of about 28 to 31 "inches of mercury". The scale now used is Millibars both in aneroid and mercury barometers.

Yes, as air pressure increases, the height of the column of mercury in a barometer also increases. This is because the higher air pressure pushes down on the mercury in the barometer, causing the column to rise. Conversely, lower air pressure will cause the column of mercury to fall.
