We weren't there; NOBODY was. There was nothing at the moment of the Big Bang, and we cannot be certain of what came into existence or when in the seconds, minutes or hours following the event.
So, "immediately"? We believe - based entirely on poorly-understood mathematical theories for which no practical test is possible - that "matter", in the sense of protons, neutrons, electrons, and their corresponding antiparticles, probably did come into existence within a few seconds of the event.
it was too hot
Immediately after the Big Bang, the universe was extremely hot and dense, consisting mainly of a quark-gluon plasma, where protons and neutrons did not yet exist. As the universe expanded and cooled, quarks combined to form protons and neutrons, but it took several minutes for these nucleons to bond with electrons to form neutral atoms. This process, called recombination, occurred when the temperature dropped sufficiently for electrons to combine with protons and form hydrogen and helium, allowing atoms to exist in a stable form. Prior to that, the intense energy and radiation prevented stable atomic structures from forming.
Three minutes after the Big Bang, the universe had cooled down enough for protons and neutrons to begin combining to form the first atomic nuclei, a process known as nucleosynthesis. This marks the beginning of the era of light nuclei formation in the early universe.
The first types of particles produced by the Big Bang were quarks and leptons. Quarks combined to form protons and neutrons, while leptons included electrons and neutrinos. These fundamental particles emerged during the early moments of the universe as it cooled and expanded. Eventually, protons and neutrons formed atomic nuclei, leading to the creation of hydrogen and helium.
Protons are subatomic particles with a positive electric charge, found in the nucleus of atoms. They are one of the primary constituents of atomic matter, along with neutrons and electrons. Protons were formed during the first moments after the Big Bang through processes involving the cooling and combination of quarks, which are elementary particles. As the universe expanded and cooled, these quarks combined to form protons and neutrons, leading to the creation of atomic nuclei during the process of nucleosynthesis.

Yes, it was during the Hadron Epoch.
They formed early in the big bang before matter and energy decoupled.

Hydrogen was formed in the early universe through a process called Big Bang nucleosynthesis, where protons and neutrons combined to form hydrogen nuclei. It is the most abundant element in the universe, created during the first few minutes after the Big Bang.
Quarks and leptons are produced immediately after the big bang.

The currently accepted model of the Big Bang predicts that the early universe was composed of a quark-gluon plasma. After it cooled, baryons could form (baryons are particles like protons and neutrons which are made of quarks), and some time after that atoms could form. If you mean which was DISCOVERED first, atoms, by at least a couple of centuries.

Protons are formed from quarks, which are fundamental particles. Specifically, a proton is composed of three quarks: two up quarks and one down quark, held together by the strong force mediated by gluons. During the early moments of the universe, quarks combined to form protons and neutrons as the universe cooled down after the Big Bang. This process is part of nucleosynthesis, where protons and neutrons later combine to form atomic nuclei.
Hydrogen was formed in the early universe, around 3 minutes after the Big Bang during a phase known as Big Bang nucleosynthesis. At that time, the extremely high temperatures and pressures allowed for the fusion of protons and neutrons to form hydrogen nuclei.
