Because energy is related to the Atomic Mass of the substance (1/2 mv^2 and all that). So, at the same temperature a more massive substance has a greater thermal energy.
Yes. In general, the more dense a material is, the longer it will retain heat, thereby containing more thermal energy. If one cubic inch of marshmallow is set in an identical environment as one cubic inch of iron, the marshmallow will have run out of thermal energy long before the iron. Size matters as well. Two objects of identical material are set in an identical environment; one cubic inch of iron, and two cubic inches of iron. The two cubic inch iron will retain its heat longer.
Probably not, depending on precisely what you mean by "sizes".
Temperature is essentially a measure of thermal energy per amount of matter, so an object which is heavier has more matter to spread the thermal energy around in. Its temperature will be lower.
An iceberg has a lot more thermal energy than a teapot, even though the iceberg is frozen and the teapot may be boiling hot.
Yes, if they are in a different state, most likely a liquid or a gas. Thus water can be held liquid at higher temperature than 100 degC, by maintaining a high pressure, whilst at a lower pressure it will turn to steam. Thus at the same temperature the same substance, in this case water, can be either a liquid or a gas, and these two states will have different thermal energies for the same mass.
Yes.
Since temperature is the average kinetic energy of all of the particles (i.e., thermal energy/mass) and thermal energy is the total, two objects of different mass and different internal energies can have the same temperature.
Also, another way of looking at it:
If you have two objects of the same temperature and different masses, and multiply that temperature by the masses of the objects, you will get their thermal energies, which will be different for both objects.
If two pieces of the same kind of matter in the same temperature have different thermal energy then there is a difference in mass of the pieces.
No,two objects at different temperature does not have the same thermal energy because both objects have different temperature .object with high temperature has more thermal energy and the object with low temperature has less thermal energy.
Heat
The thermal conductivity temperature of different objects vary from one object to another. When the two objects are placed together, there will be a change in temperature through heat conduction.
A transfer of heat (H) energy does not occur without a temperature differential. If the two objects had different amounts of H then a transfer would indeed occur. In this case heat would flow from a higher to lower temperature object.
No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.No, there will only be a spontaneous transfer of heat if the objects are at different tempratures.

It will be having different temperature, but same thermal energy and same temperature, but different thermal energy

Specific heat capacity
You have to have two objects at different temperatures near each other, when two or more objects have the same temperature.
All thermal energy flows from high temperature objects to low temperature objects. This is the nature of thermal energy.
