Therma losses are heat losses, or losses of heat energy. Just one example is the idea of thermal loss through windows in a structure. Walls can be insulated, but heat energy can pass readily through ordinary window glass. On a cold day, there are a lot of thermal losses from a structure through regular glass windows.

A simple electrical radiator. Electrons moving inside the resistor at high speed will collide with the "walls", therefore increasing temperature. Even a standard light bulb works like that. Electrons inide the filament (which is just a thin resistor) collide with the walls, producing both light and heat (actually, more heat than light is produced).
It can be if the substance bearing the heat is in a completely vacuum tight container and it isn't touching the walls of the container and there's no connection between the substance and the walls of the container. Actually no, stored energy is not heat energy and is called potential energy or chemical energy.

Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.

Thermal insulation of walls and ceilings, double or triple glazing of windows
Usually it's a foam type insulation between the refrigerator walls. Most of the times simple Styrofoam. To prevent condensation the walls often have a semi-vacuum environment.
Concrete is not a good insulator. Concrete has a high thermal mass, which means it can store and release a lot of thermal energy (heat). This property is sometimes mistaken for insulation because it can be used to delay the transmission of thermal energy. The amount of delay is proportional to the thickness of the concrete. An example of this is the use of thick concrete walls to store thermal energy during a hot day and release it during the cooler night. For a delay of this length (half a day) the thickness of the concrete wall needs to be between 150-200mm.

Most thermal pots use a vacuum flask inside. The inner and outer walls are separated by a vacuum. The only way heat is transferred from inner to outer walls is by radiation.
thermal vision allows us to see through walls. thermal power is obsolete!
