No, a leading zero is NEVER a significant digit.
Leading 0s are not significant digits, nor are trailing 0s after a decimal point in some situations. For example in 01000.01000, the first 0 is not significant as it can be left off without impacting the number. The final three 0s can be significant in some cirmcumstances, such as precise scientific measurements, or non-significant as they do not alter the number's value of 1000.01
If I understand this convoluted sentence correctly, then think it is true.
I'll assume you're asking about zeros. Zeros appearing anywhere between two non-zero digits are significant. In the other two cases they could be, but are not necessarily significant.
That is correct.
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.
It can be.
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.
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.

When the last digit of a significant digit is 5, you always round up.
