Both. It's a scale that covers a wide range of temperatures.
No, in Celsius temperature scale, lower temperatures are colder and higher temperatures are hotter.
Yes, -8 degrees Celsius is lower than -1 degree Celsius. The higher the negative value, the lower the temperature.
Yes, a higher number in Celsius indicates a higher temperature compared to a lower Celsius number. Temperatures are measured using a scale where zero degrees is the freezing point of water and 100 degrees is the boiling point of water.

I do not know how you define, "higher", but 19 degrees, C is 9 degrees colder than 28 degrees, C.
-6 Celsius is lower
Water is a solid when it's 0 degrees Celsius or lower and a liquid at 0 degrees Celsius or higher and when it is 100 degrees Celsius it turns in to a gas
It is 28 degrees Celsius that is higher than 25 degrees Celsius
Sure, a simple question to confirm if the temperature is not 30.4 degrees Celsius would be: "Is the temperature higher or lower than 30.4 degrees Celsius?"
Yes, the more lower the temperature is, the more colder it is.
18 degrees of the Celsius (or absolute) scale
It's our Autumn temperatures are mild, temperatures ranging from 17 degrees celsius to 30 degrees celsius. It can be lower or higher depending on what part of Australia you are in.
