Surcrose, Calcium chloride and Aluminum Chloride are solids at room temp.
So its a toss up between methonol and ethanol.
I look up data in a moment.
Ethanol = -114.3 C
Methanol = -97 C

lowest to lower: methanol, ethanol, sucrose, aluminium chloride, calcium chloride
reason: the first 3 are covalent molecules, so lower freezing point. Among the 3, the biggest molecule has the highest freezing point. For the last 3, they are ionic molecule, so higher freezing point. Among them, the biggest has the highest freezing point.

Ethanol: -114.1 degrees celcius has the lowest freezing (melting) point, followed by Methanol: -98 degrees celcius
then Sucrose: 191 degrees celcius
then AlCl3: 194 degrees celcius
then CaCl2: 782 degrees celcius.
