Yes, shingled areas should be at least 4/12.
A 12/12 is 45 degrees. If you set a 45 degree piece of wood on the roof it should be level.
Roof pitch is rise and run. So if you have a 4/12 pitch, for every foot of run the roof rises 4 inches.
In general, talking about roof pitch, I have never heard or read about this term being used. Roof pitch is measured when you start at the leading edge of a roof and measure towards the center of the house too 12 feet. Pitch is measured from a imaginary parallel level line at the 12 foot mark, how many feet high the roof is at 12 feet is the pitch of a roof. If your roof is at 4 feet high at the 12 foot mark then the phrase would be- a 4/12 pitch.
26 square feet? That is not a roof that is a patch. 5' X5' is 25 square feet, so a minimun job call for a roofer, about $100
10 square, 11 will ensure you have enough.
You still need to indicate the pitch, the roof sheathing, and the shingle weight.

We were looking at shingle samples for our new roof.
yes it should be removed. the new metal roof acts as its own drip edge
A shingle...
Technically the dye lot needs to be the same in order for the shingle to match exactly. With some shingle colors you really wont notice and depending on the pitch of the roof you wont notice either. However if you have a steep pitch where you can see the roof from the ground, you will notice color variations in different dye lots. In order to use same shingle colors with different dye lots the shingle installer must stagger the colors within each other to break up the differences. This will actually make the installation look very sharp.
Depends on the type of roof and type of shingles used.
The best method for cleaning a shingle roof using a shingle roof cleaner is to follow the manufacturer's instructions carefully. Typically, this involves diluting the cleaner with water, applying it to the roof surface, letting it sit for a specified amount of time, and then rinsing it off thoroughly with a garden hose or pressure washer. It is important to wear protective gear, such as gloves and goggles, and to work on a cool, overcast day to prevent the cleaner from drying too quickly. Regular maintenance and cleaning can help extend the life of your shingle roof.
The recommended overhang for a roof shingle is typically around 1 to 1.5 inches. This helps provide proper protection for the edge of the roof and also enhances the overall appearance of the roof.
rule of thumb "job cost" double the cost of material add 20%
It really depends on the size of the roof and how long you have to work on it.
