It's all in the structure
Yes, atoms of different elements have a different number of protons.
Because different elements have different numbers of protons, which determines the atomic number.
You can make a huge number of different paintings from a palette of a small number of different paints. The electron configurations that surround and control the behaviour of the hundred or so elements control the properties of the compounds that they can form. or perhaps consider the number of stories that can be composed on a typewriter with 26 keys...

Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
A finite set or a countably infinite set.
Isotopes are atoms of the same elements with different number of neutrons.
No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.
Different elements have different numbers of protons. The number of protons identifies the element.
No two different elements will have the same number of protons.
Atomic number is unique. It cannot be same for different elements.
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Most physical and chemical characteristics of a substance relate to the nuclei's neutron-proton composition. The number of protons in a nucleus is the atomic number (Z) and establishes the chemical identity of the atom. Each atomic number corresponds to a different chemical element; there are now approximately 106 known chemical elements that correspond to nuclei containing from 1 to 106 protons.
