What are t test and F test In which situation these are applied?

Both are parametric test.
The t-test uses a test statistic that is related to the sample mean(s) and is used to compare that with the mean of another sample or some population.
The F-test uses a test statistic that is related to the sample variance and is used to compare that with the variance of another sample or some population.
Both tests require identical independently distributed random variables. This ensures that the relevant test statistics are approximately normally distributed.

What statistic measures data variability in both groups in an independent t-test?
It appears that you might be referring to a situation in which Welch's t-test can be applied. Since it would be excruciating to write the required formulae here on answers.com let me refer you to the wikipedia page.

When data is normally distributed which test can be taken?
The answer depends on what is being tested: the t-test, F-test, Chi-square, Z-test are all commonly used with the Normal distribution. There are many others.

What is F ratio?
Computing F-ratioThe F-ratio is used to determine whether the variances in two independent samples are equal. If the F-ratio is not statistically significant, you may assume there is homogeneity of variance and employ the standard t-test for the difference of means. If the F-ratio is statistically significant, use an alternative t-test computation such as the Cochran and Cox method.
