There are two types of significant figures, measured and exact. Numbers are often rounded to avoid reporting insignificant figures. Numbers can also be rounded merely for simplicity rather than to indicate a given precision of measurement.
All three of them are significant figures
Temperatures are typically measured with 1-2 significant figures, as precision beyond that is usually not needed for everyday purposes. However, in scientific contexts, temperatures can be measured with more significant figures depending on the sensitivity of the measuring instrument.
The number of significant figures should be equal to the significant figures in the least precise measurement.
642000 expressed as four significant figures is 6.420e5
28.71
the measured quantity with the least number of significant figures. For example, if you multiply a quantity with 3 significant figures by a quantity with 2 significant figures, your result should have 2 significant figures.
significant figures.

Four, assuming that 7.000 is written in that form to indicate that it has 4 significant figures.
Yes, significant figures in a measurement represent the precision of the measurement. The more significant figures a measurement has, the more precise the measurement is considered to be. Significant figures help communicate the level of precision in a measured value.
