A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
Yes, machines can transform energy from one form to another. For example, a generator can convert mechanical energy into electrical energy. Similarly, an electric motor can transform electrical energy into mechanical energy.
Wind turbines transform the kinetic energy of the wind into mechanical energy by spinning the blades. The mechanical energy is then converted into electrical energy through a generator, which is then sent to the grid for use.
The four forms of energy that electricity can transform into are heat energy, light energy, mechanical energy, and sound energy.
The muscles of a runner transform chemical potential energy stored in glucose molecules into mechanical energy for movement.
A dam does not transform mechanical energy from the motion of water into electrical energy. A turbine can convert the kinetic energy of moving water, coming from a dam, a river, or anywhere, into mechanical energy, which a generator then takes to convert that into electrical energy.

The generators transfer mechanical energy into very useful electrical energy.

It doesn't. It converts electrical energy to mechanical energy. Electricity drives the rotor which has inclined blades these move the air.

You can transform thermal energy to electrical energy in a power plant, chemical energy to mechanical energy in an internal combustion engine, or nuclear energy into thermal energy in a nuclear reactor. These are just three examples.
