GeV (giga-electron-volt) is simply a unit of energy, often used for subatomic particles. Because in the subatomic world the mass-energy equivalence is much more obvious than in the large-scale world, it is often also used as a unit of mass. MeV/c2 or GeV/c2 is technically more correct, but the c2 factor is often implied, i.e., omitted.
GeV (gigaelectronvolt) and MeV (megaelectronvolt) are units of energy used to describe particle energies. 1 GeV is equal to 1000 MeV. Therefore, GeV electrons have higher energy than MeV electrons. These units are commonly used in particle physics to describe the energy of subatomic particles.
Because they needed to produce a collision with an energy around 200 GeV, the top quark's rest mass, to pop it into existence. There are currently only two accelerators in the world that can do this, the LHC at CERN and the Tevatron at Fermilab. As a point of reference, a mass of 200 GeV/c2 is about 200 times more massive than a proton.
Hadrons are composed of 3 quarks. Protons and neutrons are hadrons. The 2 types of quarks used in this instance are up quarks and down quarks. Yes, there are quarks in a nucleus.
Up quarks and down quarks are in protons and neutrons.
Quarks. There are three quarks in a proton.
The proton mass is approximately 0.938 GeV.

Like all sub-atomic particles, quarks do not have a radius in any meaningful sense. In other words, they are NOT like ball bearings for which you can say, "At this distance from the center of the quark, you are inside the particle, while further out you are no longer inside the quark." At the level of a quark, to speak of its size is to discuss a property with no meaning. Quarks do have mass, but they contribute very little mass to the particles that are made up of quarks. Most of that comes from gluons.
The mass of the Higgs boson is sometimes given in Gev (which looks gigaelectronvolts, a unit of energy, but in this case, it's not.) Physicists are using the equation e=mc2, to relate the energy to the mass. The real units they are using are GeV/c2, but the c2 is sometimes left off as a kind of shorthand. Physicists use this unit because the mass of the Higgs boson is very, very small. Units of GeV/c2, make numbers easier to work with. The mass of the Higgs boson is determined to be about 125 GeV/c2, which is equal to about 2.24x10-22 grams. It is much easier to work with (and understand) a number like 125 than a number like 2.24x10-22.

In an atom, the neutrons and protons are made up of up quarks and down quarks. Strange quarks, charms quarks, top quarks, and bottom quarks also exist, but do not play as much of a role in the structure of an atom.
Hadrons are composed of 3 quarks. Protons and neutrons are hadrons. The 2 types of quarks used in this instance are up quarks and down quarks. Yes, there are quarks in a nucleus.
1.007 Atomic Mass units, or about 0.938 GeV.
