Standard deviation is a measure of how spread out a set of numbers are from each other. It has a variety of uses in statistics.
Standard deviation in statistics refers to how much deviation there is from the average or mean value. Sample deviation refers to the data that was collected from a smaller pool than the population.
Variance. However, in fact the standard deviation is calculated from the variance, not in the order that the question seems to suggest.
Usually s means standard deviation of a sample.
A standard deviation in statistics is the amount at which a large number of given values in a set might deviate from the average. A percentile deviation represents this deviation as a percentage of the range.

Yes.
Standard deviation can be calculated using non-normal data, but isn't advised. You'll get abnormal results as the data isn't properly sorted, and the standard deviation will have a large window of accuracy.
No. Variance and standard deviation are dependent on, but calculated irrespective of the data. You do, of course, have to have some variation, otherwise, the variance and standard deviation will be zero.

Deviation, actually called "standard deviation" is, in a set of numbers, the average distance a number in that set is away from the mean, or average, number.
It is the estimate for s, the sample standard deviation.
Usually s means standard deviation of a sample.
