Relative humidity expresses a percentage of humidity in the air to the maximum amount of humidity that could be in the air.
For example: when the temperature rises the air will be able to hold much more humidity so the relative humidity will drop.
Dew point is the temperature when (invisible) water vapor in the air starts to condense. Relative humidity is the amount of water in the air. If someone knows the relative humidity, they can compare it to the dew point and figure out how wet it will be or if it will rain.

Nothing - the dew point depends on the moisture content of the air.
the relative humidity goes up cause the air is dry
The relative humidity decreases

When the relative humidity reaches 100%, the dew point and air temperature are exactly the same and the weather is extremely humid and it is possible that it will be raining

relative humidity is the AMOUNT of water in the air. Dew Point is the TEMPERATURE at which the water vapor in the air is turned into liquid water.
at 17% relative humidity the dew point is -5.8C at a dry bulb of 20C

Temperature, barometric pressure, wind speed and direction, precipitation, and humidity and dew point.
When the relative humidity and dew point temperature are the same they form clouds.

I really don't think that's the convention for these regions - I think most places usually mention relative humidity. Dew point tends to be a more useful metric, especially for comfort in the summer.

Yes. Below the freezing point the relative humidity will indicate how close the moisture in the air is to depositing and forming frost or snow.
