Ideally 1/4" per foot minimum
Plumbing pitch is the amount of fall you have on your waste. All waste, not on a pump system, has to have fall toward the destination of the waste (septic tank, sewer, etc.) The pitch is basically a downhill tilt of the pipe it requires to drain the liquid and solid waste from the pipe utilizing gravity. standard fall on a waste pipe is 1/8 of an inch per foot. the reasoning behind this is that your solid waste runs with your liquid waste minimizing clogs and optimizing drainage.

Size of any drain is calculated by fixture units (7.48 gallons) and pitch of pipe with many codes giving a bare min sizes
There will be the connection to the sewer and the drain coming out of the house. Connect the two with PVC at the proper pitch. 1/8 inch fall per foot of length.
You should try to limit the number of downspouts. The number is really determined by the length of gutter run. If the length is over 25-30 feet you may need a downspout at each end. Otherwise you would not be able to get enough pitch or slope on the gutter for it to drain properly. Aslo look to place downspouts where the excess water can easily drain away the house and foundation.
normally 1/4" per ft
1/4" per foot
ZERO pitch
you need to know the PITCH of the drain line to give an proper answer

The high pitch noise coming from your toilet could be caused by a faulty fill valve or a worn-out ballcock assembly. It is important to have a plumber inspect and repair the issue to prevent further damage.
beacuse he need to go toilet
All roofs have a "pitch" even flat roofs have a pitch required to allow water to drain from the roof.
by calculating the fixture unit requirements and the pitch of the piping for proper drainage
The building code where I live requires a drain pipe to slope approximately 1/4 inch per foot (+ or - 1/8 inch). The recommended pitch for a 50 foot drain would be 12-1/2 inches.
