6 of them.
It has 3 because the 0's after the decimal point don't count as significant figures.
The measurement 0.0030 s has three significant figures. The leading zeros (0.00) are not significant, but the digits 3 and 0 are significant because the trailing zero indicates precision. Therefore, the significant figures are 3, 0, and the trailing zero after the 3.
4 (the internal 0's count)
significant figures are how many figures greater then zero starting at a point. for example; 784944 to 3 significant figures is 785000, where you stop at the third number, round it up or down and replace the rest with 0's.
Depending on the type of the stopwatch, divisions of: 1/10 s, 1/100 s, 1/1000 s
There are two. The two leading 0's re not significant figures.

3 significants
That depends on the context in which it is found, or the calculation(s) involved. It should have no more significant figures than the value with the least number of sig. figs.
4 significant figures.Zeros are significant if they are between two non-zero numbers, or if they are "trailing" zeros in a number with a decimal point.Eg.0.000047 = 2 significant figures4.7000 = 5 significant figures
Depending on the type of the stopwatch, divisions of: 1/10 s, 1/100 s, 1/1000 s
Trailing zeros after a decimal point are not normally written. As trailing zero s have been written they must be significant; thus 0.050200 mg has 5 sig fig.
there is one significant figure in 001 because 0's only count as significant figures when they are after a whole number and there is a decimal point. ex. there are three sig figs in 100. 1.00 and 10.0
It isn't clear what the question is. If you are supposed to multiply or divide, and if by "signification figures" you mean significant digits, do the multiplication (or division), then round to three significant digits - since the least-precise of the numbers only has three significant digits.
In Mathematics, there are 3s.f. However in sciences, this is counted as 4s.f.
