and the materials that make up each of those, what are those made up of?

Protons and neutrons are composite particles made up of quarks, which are believed to be fundamental. Electrons are believed to be fundamental.
Edit--I wouldn't say electrons are leptons exactly--they are just one kind of lepton. Both leptons and quarks (and protons and neutrons)have spin-1/2, so they are fermions.

A...Protons and Neutrons are considered to have equal mass. B...The Electron has the least mass at 1/1840th of the mass of a Proton or Neutron. C...The Proton has a positive charge, the electron a Negative charge and the Neutron (as its name implies, is Neutral). (Protons and Neutrons form the Nucleus of the atom and collectively are called 'Nucleons'.).

Protons and neutrons are baryons, and are each composed of 3 quarks.
Protons are composed of 2 "up" quarks and 1 "down" quark, neutrons of 1 "up" quark and 2 "down" quarks. The names are purely arbitrary.
Electrons belong to a class of particles called "leptons", we define an electron as a negative charge, which balances a protons positive charge. Neutrons exhibit no charge, they are neutral.

Protons are made of quarks, a neutron is a proton with an electron embedded in it, an electron is just an electron.

In the Standard Model of physics, an electron is a lepton, and an elementary particle, and protons and neutrons are made up out of quarks. In String Theory, those elementary particles are made up in their turn out of vibrating "strings".

Quarks and Leptons! There are 6 types of each.

They are made of quarks which are packets of condensed energy.

They are made of quarks, which are made of energy. Everything in the universe, therefore, consists entirely of energy in the form of matter.

They are made up of quarks...which come in flavors....but no one knows what the quarks are made of....indeed...no one knows what any of the particles are made of. In my unscientific opinion, the particles are made of the fifth force, as yet undiscovered........
