Auto correlation is the correlation of one signal with itself. Cross correlation is the correlation of one signal with a different signal.
positive correlation
Faunal Cross-correlation is the use of animal bones found within an archaeological site to determine a relative date.
correlation is a technique of correlating two signals with each other and producing the third signal. In correlation if two different signals are used it is called cross correlation and if same signal is correlated with itself it is called as auto correlation.

There is no real correlation between Red Skull's double cross and Christianity or Slovakia.
positive correlation-negative correlation and no correlation
No. The strongest correlation coefficient is +1 (positive correlation) and -1 (negative correlation).
The correlation can be anything between +1 (strong positive correlation), passing through zero (no correlation), to -1 (strong negative correlation).

If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
No.
