If you sample at more than the Nyquist frequency (one half the signal frequency) you introduce an aliasing distortion, seen as sub harmonics.

What is the difference between sampling frequency and frequency?

frequency is simply the rate at which something is happening, ie the frequency of Christmas is once a year, the frequency of having breakfast is once a day etc. If frequency is expressed in Hertz, it's how many times something happens during a second. Sampling is, well, sampling. Usually means testing and measuring something changeable. If you're running a bath and occasionally stick your fingers in to check the temperature, then that's sampling, Sampling frequency simply describes at which rate you're making whatever test or measurement it is you're talking about.


What happens to the sampling error when the sample size is increased?

It is reduced.


If sampling frequency doubles then?

not sure what your asking, but if you are asking what i think your asking, you have to sample at least at twice bandwidth of the frequency you are sampling. This is known as Nyquist Rate http://en.wikipedia.org/wiki/Nyquist_rate


What is the lowpass filter cutoff frequency that must be used to decimate to reduce the sampling rate from 8kHz to 4kHz?

2kHz - That's the nyquist frequency at a sample frequency of 4kHz.
