Any element can become a solid at a certain temperature so yes, it can become a solid.
No. Only solids sublime, as sublime means to go from a solid directly to a gas. Ethanol evaporates.
I think what happens is a simple precipitation. Calcium acetate isn't soluble in ethanol, and hence crashes out of solution when ethanol is added to a saturated solution of calcium acetate.The precipitation is quick, leading to small strands of solid Ca(OAc)2, forming a solid gel. A gel consists of a continuous open network and a solvent. The network can be either solid or soluble in the solvent.

A tincture is a solution; in this case the solvent is ethanol or water.
Yes, evaporation, melting, and freezing are all physical changes. For it to be a chemical change, the substance would have to become a different substance. Evaporated ethanol is still ethanol, it is just in gas form.

Ethanol is an alcohol and is liquid and flammable. Calcium ethanoate is the salt produced by reacting ethanol and calcium metal. It is a solid in pure form.
ethanol
Ethanol would be a gas (vapor) at 1000 degrees Farenheit, Centigrade or Absolute (Kelvin).
An ethanol fire is extincted with carbon dioxide or solid chemicals extinguishers.
