1/8 inch fall for every foot of run is the ICC code minimum, but I would prefer 1/4 inch fall.
You can put up to a 2 inch pipe into a 4 inch. If you are putting 4 inch to 4 inch, either take out a section of the cast and put the PVC in or cut out a section and connect the PVC to the cast with rubber sleeves meant for this. You can use a saddle clamp for the 2 inch. It is a half round piece of PVC with a 2 inch connection in it. It is held on with two U bolts that go around the cast pipe. Put it where you need it and mark the 2 inch hole on the cast. Drill a series of 1/8 inch holes around this circle. when you get them all drilled, you can break out the plug. Try to keep it from falling into the cast pipe. Put the saddle clamp on and connect the PVC pipe as needed. Seal the saddle clamp to the cast pipe with plumbers putty.
Nope, should be 4" to prevent hoarfrost

Pipe-to-soil potential is the potential of a pipeline at a given location.
What kind of pipe? Is this area exposed to acid rain?
A pipe extended above the roof level is a soil pipe.
The weight of 1 square inch of soil can be any positive number. It simply depends on how high the 1 square inch column of soil is.
Soil pipes and waste pipes differ in their purpose and the type of waste they handle. A soil pipe is designed to carry human waste and toilet paper from toilets to the sewer system or septic tank. A waste pipe, on the other hand, is designed to carry other types of waste, such as water from sinks, showers, and washing machines. Waste pipes can also carry food waste and other debris from garbage disposals. Additionally, waste pipes are typically smaller in diameter than soil pipes.
No, that is why it is called a vent pipe not a soil line
Minimum 1/8" per foot grade.

Application before seeding and before transplanting, in the fall or spring and per soil analyses describes the minimum fertilizer requirement for capsicum plants. Peppers grow nicely when compost or fertilizer is mixed into the soil during the seeding or transplanting stages. They respond well to autumnal or spring treatments as long as nitrogen is low in the soil and per the results of soil nutrient analyses.
