The solution is homogeneous.
They are homogeneous. But they are not a mixture, so they are a pure substance
Iodine water is a homogeneous mixture because Iodine gets completely dissolved in water. A heterogeneous mixture is a mixture in which all componets of the mixture aren't the same phase.
Tincture of iodine is a homogeneous solution.
Iodine is an element, so a pure substance, not a mixture, (so even not homogeneous).
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.

A heterogeneous mixture is a mixture of two or more substances that are not uniformly distributed. The iodine and water in the question are not homogeneous because they are not uniformly distributed.

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

Yes, it is heterogenous.
Tincture of iodine: a mixture of elemental iodine and sodium iodide solved in ethanol and water.
This tincture is a homogeneous solution.
