Burning of fuels is a chemical process.
No. State change is a physical reaction.
Correct, any phase change is considered to be a physical change.
Yes, whenever a substance changes its physical form without changing the chemical composition, it is considered a physical change. In this case, liquid butter turning hard does not become a different substance, so it is a physical change.
A solution turning cloudy is evidence of a chemical change.
Fire is not a physical or chemical property. Fire is not a property. Fire is a chemical reaction where oxygen combines with some or all of the chemical components of the fuel, emitting light and heat.

water turning into ice
Assuming you mean liquid water turning into gaseous water, that is a physical change, because it's still water (H2O.)
