There are three significant digits. I am not sure what scientific digits are!
There is no such thing as scientific digits. There are 6 digits in the number of which 3 are SIGNIFICANT (not scientific) digits.
5.4 x 102.
1000 trillion is written as 1,000,000,000,000,000, which contains 15 digits. In scientific notation, it is expressed as (1 \times 10^{15}).
One digit
Yes they are, if they are large numbers. You do not need to count how many digits there are.

540 what?
There is no way to know how many significant digits are in 33000. If you are forced to choose then there are 2 significant digits but, again, there is really no way to tell. If the count of significant digits is important, the number should be expressed in scientific notation.

One digit
270 of them.
The answer depends on what 540 refers to.
540 ÷ 60 = 9
In scientific notation that number would be written as 7.080 x 10-3 and it would have four significant digits.
The "fancy" name for fingers and toes is digits.
To find out how many times 3 goes into 540, you would divide 540 by 3. The result is 180, which means that 3 goes into 540 180 times. This can be calculated by dividing 540 by 3, which equals 180.
