I heard this, and wonder is that true? If so, when you pour boiling water on packet cold-remedies such as 'Lem-Sip' which contain a lot of vitamin 'C' does it reduce/elliminate the efficaciousness properties?

NO
The reaction you're talking about is chemical, rather than magical. That means it takes time, so if you drink the solution straight away, there isn't a much chance for the reaction to happen.
It also means that you need to have the reagents in contact with each other. Ascorbate (vitamin C) is an anti-oxidant, and heat degrades it by speeding up its oxygen uptake. Boiling water bubbles, but this is mainly expanding steam. The dissolved oxygen is driven out of the water as it gets hotter.
So by the time the water is boiling, there is very little free oxygen left that would react with the Vitamin.

Yes, that is right. Vitamin C, lemon or other fruits that contains vit. C or B complex is not recommended to be boiled or threated with hot water, because of destroying these vitamins.

Yes it does.
Many vitamins are destroyed due to heat. That is why it is not so good to over cook vegetables and such.

Yes, but our body temperature never is 60C
