What is wrong if after replacing 3 sections of the cold water supply the toilet and tub don't get cold water pressure upstairs but the sinks and shower are fine and they're all on the same line?
Depending on the distance the pipe runs 3/4 inch pipe should be supplied to the plumbing location with 1/2 inch lines branched off to individual fixtures. I have also seen incidents where to much solder could cause restrictions,and even break off inside the pipes and clog shutoff valves and plumbing fixtures.
What is high pressure valve?
A pressure valve is usually installed on water systems to prevent excess water pressure from destroying fixtures or other plumbing components. When the pressure exceeds the valve ratings the valve opens and releases water/pressure from the line.
How many fixtures can you have served by a half inch cold water line?
It depends on the plumbing code in your hometown. But realistically, I have seen houses with a 1/2 inch waterfeed supply 3 families. The bigger the diameter of the pipe, the more volume will incur in the dwelling. More than likely better to run 3/4" to each bathroom group with the last tee to your toilet.

Will your water softner not regenerate effect air n the water line?
If your water softener does not regenerate properly, it may result in hard water entering your water lines, which can potentially lead to mineral buildup in your pipes and fixtures. This may not directly affect the air in your water line, but it can impact the overall water quality and efficiency of your plumbing system. Regular maintenance and proper functioning of your water softener are essential to avoid these issues.

Should a plumbing contractor flush lines entering a residence before restoring water service after a repair which allowed debris to enter the line If so is this listed in the Uniform Plumbing Code?
All potable water systems should be flushed after repairs and also if left sitting for extenden periods. I'm not sure if this is in the code but its just common sense. opening a hose bib or a tub valve when the water is restored after a repir is a best practise in the plumbing trade. If you do not do this, debris can get loose and stop up the fixtures in the home, such as toilets and faucet areators, which will result in a call back; i.e. the plumber comes back at no charge. Yes he should flush the line to protect the fixtures. The chlorine that most cities and rural water companies use will disinfect the line. Some cities require a plumber to disinfect a line but trust me be careful what you ask for because it will be at the home owners expense.

Where is the water pressure regulator that is controlling head pressure be installed?
The water pressure regulator controlling the head pressure is typically installed near the main water supply line. It is usually placed after the main shut off valve and before branching off to different fixtures in the house. This ensures a consistent and regulated water pressure throughout the plumbing system.
