A flame of fire is an exothermic, self-sustaining, oxidizing chemical reaction producing energy and glowing hot matter, of which a very small portion is plasma. It consists of reacting gases and solids emitting visible and infrared light, the frequency spectrum of which depends on the chemical composition of the burning elements and intermediate reaction products.

Fire is composed of plasma and hot gas. Plasma is just a gas that is so energetic that the electrons fly off the atoms, creating ions.

The combustion products glow when heated, according the blackbody radiation profile. Red indicates a relatively cool flame, yellow a hotter flame, white a still hotter flame, and blue an even hotter flame.

According to Hindu philosophy fire is described as one of the basic element of Life. Fire and Light are not a physical matter like other elements of life - Air, Water, or Earth. This is a different way of answering your question.
Fire is not a matter. It is a form of energy, but it is supported on some combustible mater and / or generated from it because of a vigorous oxidation reaction (in most cases) and that is why we say breakout of fire. If it is under control we call it flame.

Fire is a plasma & not any of those.....it actually is a cause to turn something it liquid or gaseous form.....It converts the solid matter in to liquid & if heated further will result in gas !!!!

Fire is produced by the (for eg.)burning of a magnesium ribbon. Now, the flame is magnesium oxide as it(magnesiumribbon)is inflammable and combines with oxygen(combustion)
So it is a mixture of gas and solid as the electrons closest to the material which burns is highly exited and as we go away from the flame it is mainly gas and a bit of ashes.

Fire is plasma.

Plasma:In physics and chemistry, a plasma is typically an ionized gas. Plasma is considered to be a distinct state of matter, in contrast to gases because of its unique properties. "Ionized" refers to presence of one or more free electrons which is not bound to an atom or molecule. The free electric charges make the plasma electrically conductive so that it responds strongly to electromagnetic fields.

Plasma typically takes the form of neutral gas-like clouds (e.g. stars) or charged ion beams, but may also include dust and grains (called dusty plasmas). They are typically formed by heating and ionizing a gas, separating electrons away from atoms, thereby enabling the positive and negative charges to move more freely.
Plasmas are the most common phase of matter. Some estimates suggest that up to 99% of matter in the entire visible universe is plasma. Since the space between the stars is filled with a plasma, albeit a very sparse one (see interstellar medium and intergalactic space), essentially the entire volume of the universe is plasma (see astrophysical plasmas).

The flames we see from a fire represent the oxidizing gases being given off from the combustible materials.

fireplace is a gas that effects from a chemical replace. this is, a stable, liquid or gas will integrate with oxygen and launch capability, and interior the technique will replace right into a clean gas with a distinctive chemical makeup.

A rapid, persistent chemical change that releases heat and light and is accompanied by flame, especially the exothermic oxidation of a combustible substance.

it can't be accounted in any known states of matter.

Fire is better described as a reaction product. At least in my mind (which might not be the most reliable thing).
