It should be magma is the hottest b/c it is usually molten rock that has not reached the surface during an eruption.

Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.

Fire, is the most "not hot" amongst the three b/c I'm believing the "fire" type you're talking about is like a fire such as a fire for a camping trip to cook on or to keep your house warm right? If it is, then fire would be the least hot in this case. Hope that helps.I would say Fire has the higher temperature.Magma by far!Magma is the hottest. Once magma hits the surface of the earth it is called lava, and cools rapidly. The temperature for magma is at least 3000 degrees. About 10 times hotter than an average campfire, but it gets hotter.Fire has no fixed temperature. Different materials burn at different temperatures at different pressures and oxygen concentrations. Fire can get incredibly hot, hot enough to melt any metal and yes, to creat molten rock.

I think Magma is kind of hotter than lava because magma come from directly from mantle and lava is cooler than magma because when it gets in the air than it gets slightly cool.
