To correct to 4 significant figures, you need to round the number to have four digits starting with the first non-zero digit from the left. If the fifth digit is 5 or more, round up the last remaining digit. If it's less than 5, keep the digit as it is.
4 significant figures.
There are 3 significant figures in 94.2.
4 significant figures.
If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.

776,890 in four significant figures is 776,900.

The number of significant figures depends on how the number was derived. If 0.00999 + 0.00001 then it has 4 sig figs even if it appears to have only 1.

The correct answer is 2. The three zeros between the decimal point and the 1 are place holders but they are NOT significant digits. See, for example, the Wikipedia link.
