I mean like instant freeze. A person is standing in a room and the temperature can be instantly turned down to freeze the person immediately and kept at that same temp... let's say a year later, could you unthaw the person and have them come back to life? what about 100's of years later?

Possible now? No.
Possible soon? Probably not.
Possible ever, where one freezes in some special way, or prepares the body for freezing in some unknown special way? Who knows. Maybe.
We only really need our head frozen, which will slightly simplify things. We'll get any body we want when unfrozen. Perhaps a real flesh body grown without a brain, just for us!
I wouldn't shell out the dough for this quite yet.

No not freeze. Not yet anyway. It is very destructive to tissue cells because of the ice crystals that form from all the water in the body. However, the faster you freeze something the smaller the destructive ice crystals are. If that helps. Fast freezing, like with dry ice, causes much smaller ice crystals which is why it is used to fast freeze foods (because the foods taste better when the cells are not destroyed). Commonly uses on strawberries to keep them ‘fresh’. Not sure how small the ice crystals would need to be to safely freeze a live animal safely but who knows.

No. Water molecules rearrange themselves to form crystals upon freezing. This process, since humans are mostly water, causes irrepairible damage to tissues. Even if it didn't, there's no way to thaw a person out so that all tissue defrost at the same time and therefore, the outer tissues wouldn't require oxygenation while the heart and lungs are still frozen solid.

It would make more sense to try and clone them by storing their DNA.It has been suggested though that when the soul or spirit leaves the body for an extended period of time they don't usually return as if they have moved on. Some scientists claim that this energy dissipates and it also ceases to exist, or maybe that's just for scientists who don't believe in an afterlife.Cloning someone doesn't mean everything though, as you might expect. However, it has been suggested that extraterrestrials have been successful at this.(Ha) Don't you read the Internet tabloids?

Since water expands when it freezes and the human body is 90% water, the body, including the brain, is actually physically destroyed and cannot be brought back to life.

They froze Walt Disney, but it's not an instintanius freeze, otherwise the water would expand and the cells would erupt

Some people believe that and spend a ton of money to be frozen but its not possible yet. Maybe one day, but im not going to pay that much money to find out.

We don't have the know-how to do the thawing/reviving safely yet.
That technology may be coming. A beagle was chilled -- not quite frozen -- and revived. Google
frozen beagle

No. Not with current technology. May be in the future

Not yet. You can freeze sperm, or DNA, but the whole package is tough to bring back after its been frozen.
