No.
yes.
No. It will float on top
To float in olive oil the box needs to displace a volume of olive oil that has the same mass as the box - the less dense the oil (for example by being warmer) the more volume the box will need to displace to equal its mass. If it cannot displace a volume of olive oil that equals its mass, the box will sink. Or to put it another way, the box will float in olive oil as long as its density is less than that of the oil.
Yes... oil will float on top
If it is lighter than the oil, it will float, if not it won't. Most plastics are about the same density of most oils. Some will float some won't.

No. Ebony is one of the few woods that doesn't float in water. Oil is lighter than water so ebony won't float in that either.
Candle wax is covalent! Olive oil is non polar covalent. Because it can not disolve in water and water is polar.
if you were to add water an ice cube an olive oil the water would be on the bottom and the oil would be on top and the ice cube wuld float inside of the olive oil.
It depends on how the ice was frozen, but ice (frozen water) will float in water and will probably have a greater density than olive oil, so it will sink in olive oil.
because the weight of gravity on the bottom of the candle makes its self float
