Yes, wax in a candle is one of the two substances that causes the candle to burn (oxygen is the other.) The reactants are therefore wax and oxygen, and the products are carbon dioxide and water vapor (and heat/light.)
Yes, wax candles are a fuel.
Yes it is.
Candle wax is the fuel a candle uses to keep burning. So, I guess the effect of the wax is the candle keeps burning.
It really depends on what you are using the fuel for. If you want a liquid fuel that easily vaporizes in a carburetor to make an explosive mixture with air and burns quickly to release a lot of energy, then petrol is better than wax. I you want a less dangerous fuel for a candle, one that melts and vaporizes to burn slowly in air, then wax is what you want. The reason for the different burning properties of petrol and wax lies mainly in the size of their molecules and how the carbon and hydrogen atoms in them are joined together.
No. Today it's quite rare to come across an all-wax candle. Most are mixes.

Melting is a change of state from solid to liquid. Burning is reacting a substance with oxygen, otherwise known as combustion.

The lighted candle burns wax for fuel. The heat from the flame melts the nearby wax, and it is drawn to the flame through the wick. The wick is slowly consumed by the flame, but the wax is the main fuel.
the fuel produces has higher ignition temperature and produces more heat
The liquid wax. Once the candle melts the wax around the wick, it draws it up through the cloth wick in order to fuel the flame. Oxygen is also required for the candle to burn, but it is not the fires fuel source.
The candlesticks are probably what you're referring to, in which case the fuel is the candle wax.

When the candle flame is burning, the flame heats the wax which melts it, the wick pulls in the liquid wax into the flame as fuel (this is why the wick doesn't just burn away). Think of a napkin soaking up water. The wax then burns in the flame and "disappears".
