If you ever tasted ice that melted in a drink glass you would know it tastes “flat”. that is because freezing the ice cubes tends to eliminate the dissolved air. that is why faucets have an “aerator” to prevent the water from tasting flat.

quiescently freezing water does change its composition. the first that is frozen is very pure water, the last to be frozen has the most contaminate. quiescently freezing is a technique used in the lab to help concentrate trace contaminates to make analysis easier. but if you freeze all the water, then thaw all the ice, there is no net purification effect.

No, chemically speaking, this is only a physical change and it does nothing to the water. Boiling makes it better to drink, but it tastes like cr*p. If you can’t afford iodine tablets (they use them in the military and in 3rd world countries), then boil it. I find a lemon added to boiled water makes it taste a bit better, but not much.
If it’s for a machine, then no. See the chemical change above.

No, it’s not true. It will de-gas the water, because ice will hold less dissolved gasses than water does. So it will taste different, and my absorb odors from the freezer.

Did the same person tell you that hot water freezes faster than cold water?

No.
There’s a bunch of pseudo-scientific hokum out there about this sort of thing.
Freezing water will de-oxygenate it somewhat; that affects how it feels/tastes in your mouth. And it will probably make it taste like the freezer.
But, no, it does not affect how much your body absorbs. Unless you have diarrhea, your body absorbs almost all of the water you drink, passes it through the blood stream, and excretes it through the kidneys.

Cold water holds more air/gas than warm and may taste better after shaking to expose more air to it. Ice, depending on how it is frozen and maintained, can produce very stale tasting water when melted as there is little or no gas in clear hard ice.

Absorbs better? Don’t know what you mean.

The freezing would kill any small animals and most eggs in the water although not all bacteria.
