If the question asks about each type of particle, here is a general answer.
The antiproton is the antiparticle of the proton - antimatter. Though it is stable, it will combine with a proton pretty quickly, and the two particles will mutually annihilate each other releasing very high energy gamma rays (cosmic rays).
A positron is the antiparticle of the electron - and antielectron. It's antimater, too. It will combine with an electron in mutual annihilation and produce high energy gamma rays.
A meson is a subatomic particle consisting of a quark-antiquark pair. It's a strongly interacting boson. There are some 20 different types of them, too.
A muon is a negatively charged elementary particle. It can be thought of as an "overweight" electron. It is unstable, and has a mean lifetime of about 2.2 microsecnds. It will decay into an electron, a pair of neutrinos and possibly some other particles.
Links are provided to posts on each of these particles, and you'll find those links below.
A positron orbiting an antiproton would make up an exotic atom called positronium. Positronium consists of an electron-like particle (the positron) and a proton-like particle (the antiproton) bound together by electromagnetic forces. It has a short lifespan before annihilation occurs, releasing gamma-ray photons.
The anti-matter equivalent of an electron is a positron. Positrons have the same mass as electrons but have a positive charge. When a positron and an electron collide, they annihilate each other, releasing energy in the form of gamma rays.
They aren't 3 they are in fact 12 if you count anti matter as a separate particle from matter. Electron, muon, tau, electron neutrino, muon neutrino and tau neutrino. The same apply to anti matter positron, anti muon, anti tau, postrin neutrino, anti muon neutrino, and anti tau neutrino.
Examples: proton, muon, boson Higgs, positron, antineutron, tau neutrino etc.
The muon decay equation is: - e- e . This equation describes the process of muon decay, where a muon (-) transforms into an electron (e-), an electron neutrino (e), and a muon neutrino (). This decay process occurs due to the weak nuclear force, which causes the muon to change into lighter particles.
Lepton is the common name given to electron, positron, neutrino, antinuetrino, mu-meson [muon] etc. So an atom has these elementary particles within and come out in specific circumstances.
Positron, antineutron, antiproton
You probable think to antiparticles as antiproton, antineutron, positron.
Antihydrogen is the anti-matter analogue of hydogen made from a positron and an antiproton.
Examples: positron, photon, neutrino, muon, tau, Higgs boson etc.
It is meson. Hideki Yukawa named it mesotron which was later corrected to meson. Muon was the first particle that had the predicted mass of a meson. It was discovered by Carl David Anderson. It was later conclude that it was not the right particle.
A positron is the antiparticle of an electron; in other words, it is an alternate name for the "anti-electron". Therefore, a positron would anihilate with an electron. I am not sure about the "why".

Antihydrogen is a form of antimatter consisting of an antiproton and a positron (antielectron). When antihydrogen comes into contact with ordinary matter, they annihilate each other, releasing energy in the form of gamma rays. Scientists study antihydrogen to better understand the nature of antimatter and its interactions with ordinary matter.
