It can be.
Zero is considered a significant digit when it is to the left or the right of the decimal point. It is also a significant digit when it follows a non-zero digit or when it is between two digits.
True
That is correct.
No, a leading zero is NEVER a significant digit.
If I understand this convoluted sentence correctly, then think it is true.
The thousands digit is 4 left of the decimal point and the ones digit is the digit to the left of the decimal point. In a whole number the decimal point is not written and can be considered as "hiding" after the last digit - the ones digit.
All digits are significant in this case. Any digit after a decimal point is a significant digit.
All digits between the first non-zero digit and the last non-zero digits are significant. Some would argue that trailing 0s are significant since they are an indication of the precision of the number.

There are four significant figures in the number 2603000. Zeros at the end of a number are considered significant if they are to the right of the decimal point or if they are after a non-zero digit.
