Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
All substances can have a gaseous state, however, below the triple point (the temperature and pressure at which solid, liquid and gas can co-exist in equilibrium), the equilibrium is between the solid state and the gaseous state. Once you get above the triple point, you can get a gaseous state as long as you are above the melting point of the substance and below the critical point (the temperature at which the gas and liquid states have the same density - above the critical point you get a single "supercritical" phase). Between the triple point pressure and the critical point pressure, the temperature at which some liquids begin to get a gaseous state is know as the "boiling point". For water at sea level, that happens around 100 °C (212 °F) - although anyone who has been camping at high altitudes can attest to the fact that with the lower pressure at high altitudes, the boiling point of water can drop to something barely luke warm.
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
is the same
You can't alter it. A triple point is ONE set of pressure (p) end temperature (T), a physical property for each pure compound or element in all three phases together (s, l, g).
They are the same.
They are about the same.

Dew point is the temperature at which the water vapor in the air condenses, then evaporates. The barometric or air pressure is independent from the dew point.
The relationship that you expect to find between the air temperature and dew point temperature at ground level if the area is covered by fog is the temperatures of th air and the dew point would be very close in value.
The triple point refers the temperature and pressure at which the three phases of silver coexist in the thermodynamic equilibrium. The triple point of silver is 1233.95 degrees Celsius.

"triple point"
One interesting use is to define a temperature standard - the triple point of water (or any substance, for that matter) is at a very precise temperature. On the other hand, the melting point or the boiling point depends on pressure.One interesting use is to define a temperature standard - the triple point of water (or any substance, for that matter) is at a very precise temperature.

Triple point of water, where water freezes/melts
The triple point of a phase diagram is the location where the solid, liquid, and gas phases meet; it is the temperature and pressure at which a given substance can assume any of the 3 usual phases of matter.
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
