Right now, it depends on WHO is doing the counting.
Quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to build models of quasiparticles.
The quantum field theory arose from studying interactions between elementary particles and has been successfully applied to other physical systems, particularly too many body systems.
Quantum Field Theory describes a model in which every particle and force has its field stacked on each other and permeates the universe. When the field is excited, we see a particle.

Does each field have a distinct antimatter equivalent? These possibilities net us between 1 and 36 fields.
quantum field
6 for quarks (up, down, strange, charm, top, bottom)
3 for charged leptons (electron, muon, tau)
3 for neutrinos (electron neutrino, muon neutrino, tau neutrino)
1 for photon (carrier of electromagnetic force)
1 for gluon (carrier of nuclear solid force)\
Quantum field theory (QFT) has many fields, including 12 fermion fields and 12 boson fields:
Boson fields. These fields contain particles such as photons, Z and W bosons, and gluons.
fermion fields
These fields contain particles that make matter, such as quarks, electrons, muons, tau particles, and neutrinos.

Other types of quantum field theories include:

Spinor field theory
Gauge field theory
Interacting theories

BD: HOW MANY FIELDS ARE THERE?
The quantum field theory says that particles don’t exist. The fundamental entities in our best theory, quantum field theory, are fields. Quantum field theory. (2024, November 16). In Wikipedia. https://en.wikipedia.org/wiki/Quantum_field_theory. Classical fields can have arbitrary values of energy and momentum. Quantum fields are, in a sense, more constrained. We can describe their state as a sum of “excitations,” each of which has a specific frequency, not unlike music, which can be thought of as a combination of many frequencies. However, the energy levels at each frequency cannot be arbitrary. Instead, they come in set units. So when a quantum field interacts with another quantum field, the result is that its number of excitations at some given frequency increases or decreases by one.
This sounds very mathematical, of course, but here is the thing: These excitations have physical existence. For starters, they carry energy and momentum; they can communicate a physical influence between things.
These excitations can be highly localized under the right circumstances. The quantum field is highly likely to interact with other fields at a specific location and is almost unlikely to interact with others elsewhere. Here, the excitation behaves almost like a miniature cannonball or some such thing, i.e., a particle.
So yes, protons, neutrons, and quarks are “things”: they carry energy and momentum from place to place and let other things influence each other through their actions. But they are not, actually, miniature cannonballs. They can be smeared out. Indeed, suppose we allow for the curved spacetime of gravity or accelerated observers in relativity theory. In that case, two observers may not even agree on what excitations of a quantum field they see, i.e., they won’t see the same particle content (but see the same field.) But at other times, these “particles” are confined in space and, for all practical intents and purposes, behave as though they were miniature cannonballs. For instance, when the electron gun in an old-style CRT display emits electrons, they follow the route prescribed by classical physics for electrically charged particles as they travel toward the screen, influenced by the electric fields of the CRT.
When you look at what happens to a ray of light in diffraction optics, it is impossible to account for that using the notion of photons as miniature cannonballs. Instead, the field reigns supreme: you need the machinery of Maxwell’s electromagnetic field or its quantized version to fully understand what happens, how waves interfere constructively or destructively, and how a diffraction pattern forms. Yet for the actual detection of light, a photon counter still measures individual photons, even though in such an experiment, they decidedly do not behave like miniature cannonballs; instead, they are the unit excitations of the electromagnetic field, which can exist even when they have no well-defined position.
