Candles do not burn at a constant rate at all. There are hundreds of different kinds of candles. Some burn quickly and some burn slowly so there is no way of really finding a constant rate.
As long as they were all lit at the same time, they would burn for the same amount of time (regardless of the number of candles).
Generally, colored candles burn at the same rate as white candles because the colorants added to the wax do not significantly affect the burning process. The burning rate can depend on factors like the wick size, quality of the wax, and ambient conditions.
The rate at which a candle burns is dependent on the size and composition of the wick, and the thickness, composition, and melting / vaporization rate of the candle wax. The composition of the candle is far more important to the burn rate than the color.
No, they do not.
Because sometimes you walk fast and sometimes you walk slowly.

Calories are calories, no difference between then - they all burn at the same rate.
Candles are all different and burn at different rates, but the color is not a factor. The amount of paraffin/beeswax, and the thickness of the wick primarily determine how fast a candle burns.
no, you can but you dont have to all you have to do is time them and compare the times, so you can do them at different times
Yes, room temperature can affect the burn rate of a candle. Candles may burn faster in warmer temperatures as the heat can melt the wax faster. In colder temperatures, candles may burn slower due to the wax hardening more quickly.
White canldes will probably burn at a different rate than colored candles for the simple reason that in order to get different colors, candles will have different compositions - you have to put different dyes (or other color source) into candles to make some of them green, some of them blue, some of them orange, etc. etc. etc. With that said, most of the time if all you have done is add a little bit of color to the wax, it won't affect the burn rate very much. Also keep in mind that even if you do change the burn rate, you would have to know what you used to make the color in order to determine if the burn rate increased or decreased. Burn rate depends on composition. Color depends on composition. Burn rate is only indirectly related to color.
The color of a candle does not affect its burning speed; rather, factors like wick size, wax composition, and environmental conditions determine the burning rate. As long as all the candles are made with the same materials and have the same size and shape, their burning speed should be similar.
they all burn at the same rate
I dont know about what brand burns the slowest as there would be thousands of brands out there, mostly all made from the same thing but if you freeze or refridgerate your candles they will last hours longer.
Yes, tealight candles typically burn out on their own once they have consumed all the wax inside the metal holder.
Scented candles, air freshners, cleaners are all dangerous for birds. Non-stick utensils are dangerous as well.
