Iodine crystal is solid Iodine. Iodine solution is when Iodine crystals are dissolved in water.
dissolve iodine crystals in a saturated KI(potassium iodide) solution
Benedict's solution is used to test for simple sugars and iodine is used to test for starches.
The role of KI in the preparation of strong iodine solution is to enhance the solubility of iodine crystals in water. Iodine is generally not soluble in water. The KI is added to help the iodine to be dissolved. -College Chemistry professor

Starch is insoluble in water. The commonest kind of iodine solution is known as tincture of iodine, which is an orangey-brown liquid. Please see the links.
The iodine stain solution you're referring to might be Lugol's iodine. This is iodine and potassium iodide in water. The product available in a pharmacy is tincture of iodine which is iodine and potassium iodide in ethanol and water. Please see the links.
Iodine is a chemical element and contains no other substance. Tincture of iodine is a solution of iodine in alcohol, used to disinfect wounds, and contains four different elements.

They are homogeneous. But they are not a mixture, so they are a pure substance
Iodine crystals are a pure substance.
Iodine crystals are very poor conductors of heat and electricity
It's the same thing. It is a solution of water that has been saturated to the max with potassium, then iodide is added (a form of iodine). So it is a potassium iodide solution.
iodine crystals are black, table salt crystals are white.however I doubt that was your question. I think you are referring to iodized table salt. there are no iodine crystals in iodized salt, instead they add sodium iodide to the table salt. sodium iodide crystals are indistinguishable visually from the sodium chloride crystals of table salt.the only practical way to separate sodium iodide from sodium chloride is the very tedious repetitive process of dissolving the mixed salts and performing fractional crystallization of the solution.
