I was reading and... antimatter arise as the opposite from "normal" matter. What is considered as "normal" matter and also... If they say a particle that's positive has an antimatter particle that's negative, and vice versa, then would a neutral particle possess it's counter antimatter particle too?

Normal matter consists of: Up quarks, down quarks, strange quarks, charm quarks, top quarks, bottom quarks, electrons, muons, tauons, electron neutrinos, muon neutrinos, and tauon neutrinos.
(The quarks are what form neutrons and protons)
In terms of neutral particles, an anti-neuton would be formed of two anti-down quarks and an anti-up quark.
Neutrino's do indeed possess an anti-matter particle, the anti-neutrino. It's produced naturally in beta decay inside the nucleus, although I don't know much more about them than that.

"Normal" is only a matter of perspective. If there was an antimatter universe, they would consider the matter that makes up our universe as "anti-matter" and their matter "normal".
As for the neutral particles, you are correct. In fact, every single particle has an antiparticle. The best example I can provide of these particles' appearance in nature is the decay of radioisotopes:
when a proton undergoes beta decay, it releases a positron (positive opposite of an electron) and an electron neutrino (original electron neutrino, neutral charge). However when a neutron undergoes beta decay it releases an electron and an electron antineutrino, which is the opposite of the electron neutrino, but still holds a neutral charge.

Neutral particles (I believe) are their own antiparticles, but don't hold me on it.
