All you need is their temperatures. If their temperatures are different, then heat will flow from the warmer one to the cooler one.
what is the general rule for how charged objects interact
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.

they attract each other

Pencils are both materials and objects
Force arises whenever two objects interact. This force can either attract or repel the objects depending on factors such as their masses and distances apart.

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
conduction
No.
they will repel.
