sometimes have the same thermal energy

A spoon is a measure of volume. Different substances have different densities so that the same volume of two substances can have very different masses.
There is no specific name for a polygon in which all the angles are different or where the sides are all different.
The result of mixing equal MASSES of water at different temperatures will be the mean of the two temperatures. Unless you are being very sophisticated and are taking the thermal expansion into account, the same will apply to volumes.
Neither does. They're equal masses.
The answer depends on what the numbers measure. If they are the masses of equal volumes of substances, then the substance with mass 0.8 is denser. On the other hand, if the numbers refer to the volumes of equal masses of two substances, then the substance with volume 0.7 is denser.
