Diatomic Iodine is non-polar, so the reaction will likely be a solution
Yes, it is elemental iodine dissolved in ethanol.
Evaporation.
Tincture of iodine is potassium iodide and iodine dissolved in ethanol (plain alcohol).
The solution is homogeneous.
It is not iodine which is applied but a tincture of iodine. This is around 5% iodine mixed with potassium or sodium iodide, dissolved in ethanol and water. The tincture is an antiseptic.
Yes, it is elemental iodine dissolved in ethanol.

Evaporation.
Tincture of iodine: a mixture of elemental iodine and sodium iodide solved in ethanol and water.
Iodine is dissolved in ethanol at any temperature.
Tincture of iodine is potassium iodide and iodine dissolved in ethanol (plain alcohol).
Produces Sodium chloride and Iodine
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
The solution is homogeneous.
7% elemental iodine and 93% mixture of ethanol and water.
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
Povidone Iodine is a mixture of Polyvinylpyrrolidone and Iodine. Tincture of Iodine is a mixture of Elemental Iodine + KI/NaI dissolved in a mixture of ethanol & water
