The ph of natural rain water varies depending on the acidity of the atmosphere.

Around pH 6 due to the CO2 present in the air.
However, in areas with lots of cars and factories, the rain water can have a pH of 5 due to the presence of SO2, SO3 and NO2.

There is no such thing as natural rain water as the climatic conditions where it falls influences it.

it should actually be PH7 but due to acid rain etc it is slightly under..around 5 or 6

In theory, pure water is ph7. But we have so much crap in our atmosphere that it tends to be acidic. ph5-6 is more like it

it depend on what type of area it originates, ie. a peat based area would be slightly acidic producing soft water, chalk based would be slightly alkali producing temp hard water.

well rain water is acidic, so below seven, but it should be PH7.

6, 7? i suppose it depends on chemicals in the atmostphere, they don't call it 'acid rain' for nothing
