What can cause 1 light to dim when 3 others in the room are ok the light works from its own 2 way switch?
The switch sounds like it might be arcing. Switches are inexpensive, change it out with a new one. With the power off and the old switch removed check the connections in the switch junction box for loose splices or burnt wire nut connectors. If everything is fine there check the light junction box for loose connections.

Why won't my Light turn off at switch?
Presuming the switch worked at one point and just stopped working it is likely that the switch has failed in a normally closed position. The only other possibility is that somehow you have a wire problem whereby the hot side of supply is connected to the load side of the switch. This could be caused by an exposed wire in the switch receptacle. Suggest you turn off power at breaker and replace switch as a start. When you have the switch removed from the receptacle, with wires still connected see if switch works. If it does it could still be bad, but examine the wires around switch and see if you have any exposed wire that could be touching the load side of the switch (Side connected to the light).

How do you know which outlet is controlled by a switch?
Plug a lamp into a working socket of an outlet to ensure the lamp works. Then turn off the switch and plug lamp into all outlet sockets, top and bottom outlets until the lamp doesn't light.

It is possible to remove a jumper in an outlet to isolate the sockets for just this purpose. Often an electrician will install the outlet upside down (The third prong pointing up, to identify the outlet.
How dimer switsh work?
It works by sending the current through a resistor. As you twist the dimmer switch it changes the length of the resistor and the longer the resistor the more it inhibits the current. So at full brightness the resistor has been totally bypassed as you turn the light down the contact moves further around the resistor making it longer.

How does the power to light then switch work in electrical circuits?
The power to light switch in electrical circuits works by allowing or interrupting the flow of electricity to the light bulb. When the switch is turned on, it completes the circuit, allowing electricity to flow and light up the bulb. When the switch is turned off, it breaks the circuit, stopping the flow of electricity and turning off the light.
