yes
No, brass cannot be used as a dielectric union between copper and black iron pipe. Dielectric unions are typically made of materials that are not electrically conductive, such as plastic or rubber. Brass is a conductive material and would not provide insulation against galvanic corrosion between copper and black iron pipe.
Lead wipe a brass nipple into the lead pipe and then use a female adapter x PVC on the brass threads
There should be a nut around the chrome pipe holding it to the brass. Loosen the nut and pull the chrome pipe out.
No.
Not necessary, but recommended along with pipe thread compound.
Plastic pipe does not rust, brass does not rust, copper does not rust. Stainless steel does not rust, lead pipe does not rust.
In this scenario, the steel pipe will likely corrode faster than the brass tap due to galvanic corrosion. When dissimilar metals are in contact in the presence of an electrolyte (such as water), an electrochemical reaction occurs, causing the steel to degrade. To prevent this, it's important to use proper corrosion inhibitors or coatings to protect the steel pipe.

NO, PVC is very sensitive to which glue is used. In Domestic pipe applications you should use Weld-On 711

There are instances when corrosion occurs at the junction of a carbon steel pipe and a brass valve. This is often the result of a pipe threading failure.
No! That will create intergranular corrosion
Yes, it is still a pipe thread. The pipe dope is there to fill in the gaps in the thread. It is impossible to machine the treads close enough in pipe to not need something in the threads to make a seal.
Yes all brass object can be recycled.
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
It depends on the thickness of the plastic pipe. :)
