The natural rate of unemployment is the rate that holds over the long-run in equilibrium. In Classical economics, this rate is 0%. With other assumptions, such as frictional and structural unemployment, you will get a natural unemployment rate above 0%.

Cyclical unemployment rate = Actual rate - Natural rate of unemployment. if you don't have the Natural rate, then you might have Frictional & structural rate, which can be added together to get the natural one N= F+S
Natural Rate of Unemployment -The natural rate of unemployment is unemployment that does not go away on its own even in the long run. -It is the amount of unemployment that the economy normally experiences.Cyclical Unemployment -Cyclical unemployment refers to the year-to-year fluctuations in unemployment around its natural rate. -It is associated with with short-term ups and downs of the business cycle.
Natural rate of unemployment
No, the natural rate of unemployment changes.
The natural rate of unemployment is the rate which occurs when inflation is correctly anticipated. This level of unemployment occurs when the labour market is in equilibrium.
Unions may affect the natural rate of unemployment via the effect on insiders and outsiders. Because unions raise the wage above the equilibrium level, the quantity of labor demanded declines while the quantity supplied of labor rises, so there is unemployment.
The natural rate of unemployment, also known as the non-accelerating inflation rate of unemployment (NAIRU), is the rate of unemployment at which inflation remains stable over time. It is determined by structural factors in the economy, such as demographics, labor market institutions, and technology. It is not a fixed number and can vary over time.

They do, but inflation will result, the monetarist view of the natural rate is that it is the non accelerating inflation rate of unemployment (NAIRU) to move below this will result in high inflation and is therefore not worth the benefit of the reduced unemployment.
What is the national unemployment rate
The Official Unemployment rate (U-3) in US for August 2011 was 9.1.Below are the other unemployment rates in US for August 2011 :U-1 Unemployment rate : 5.4U-2 Unemployment rate : 5.3U-3 Unemployment rate : 9.1U-4 Unemployment rate : 9.7U-5 Unemployment rate : 10.6U-6 Unemployment rate : 16.2
The natural rate of unemployment cannot equal zero, because there will always be people seeking full time employment, because they are dissatisfied with their present job, or are newly in the workforce, etc. and hence are unemployed.
