Heat
If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.

(thermal) equilibrium
Heat energy will be transferred from the hotter objects to cooler objects until they are all at the same temperature.
It's not. A difference in temperature is required in order to drive the transfer of heat.
If those two objects are in contact with each other, they will come to thermal equilibrium, at a temperature some place between the original temperature of the two objects. The actual final temperature will depend on the specific heat capacity of each object, the mass of each object and the temperature of each object.
Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).
Heat is the amount of energy transferred between objects where a difference in temperature is present. So in that sense, heat is related to temperature differences, but is not the same. The temperature difference is caused by the difference in the avg. speed of particles between the two objects.
You have to have two objects at different temperatures near each other, when two or more objects have the same temperature.
