There is no special PVC pipe. CPVC can be used for hot water applications or in my opinion just use PEX pipe.
Fire bricks or kiln bricks.Any grey cement will do.
You can use one of the cleaners available in the market to clean the water pipe line.
PVC pipe is an acceptable product to use in chillers that contain glycol. You should never use galvinized pipe where glycol is used. Copper is acceptable as well.
No, PVC is quite resistant to chemical attack. If you use the acid properly, you shouldn't have to worry about it at all.

Use teflon tape with a little pipe dope. If you don't ever have to take apart again then you can use glue which you are calling cement
no, use CPVC instead.
Hot? Cold? return? fire suppression ? Non Potable?
I would use hot water conn. on it. Both on cold and hot
Sure hot water heaters use them and they take the heat. However, this might not be up to building codes. Either check the building codes for your area, or be aware that you might have to replace it again in the future.
always use copper for any kind of water installation
Yes, copper piping is usually recommended for both hot and cold water systems.
PVC can take hot water like any other pipe but the reason no one wants to use it on hot water lines is because the glue joints can not take hot water so if your talking about straight pipe then it will be ale to take 212 degrees but if your talking about pipe and glue joints then it will fail around 65 + degrees F . If you want to run hot water in PVC you can use CPVC and the glue joints an pipe can with strand 212 degrees F but after some years as I have seen the pipe gets real brittle and so i always recommend the best called Wirsbo or any class AA pex
Not sure what you're asking. Do you need to know size of piping or what kind of pipe to use?
This is a sign of residue in the hot water pipes. i guess at your part of the world, you must be using corrosive type of water pipes. The heat in the water helps oxidization of the inside of pipe and when the same pipe is not used to transfer of water in the pipe, existing water in the pipe caused corrosion so when the tap is opened after a while, the water that comes out is brown. To avoid this, you need to use the tap more often to stop the brown build up inside the pipe.
UPC does not permited PVC to be used for potable hot water. So don't put it inside the house. IF you have o use plastic pipe use PEX of CPVC both of which are OK for hot potable water. In answering you question PVC can handle 120 degree water temps
