My friend and I where talking about this today and he has an ac and wants to keep it at 76. so we where in his place and he said it was still warm for him so i said why not turn your ac to maybe 72. and he said it wouldn't even matter if he did. is this true? or will it make the room a bit cooler?

The thermostat setting is the target temperature the unit will try to achieve. If you set the thermostat to 76, it will remove the heat from the area until it reaches 76, then it will rest. When the temperature rises to 78, it will turn on and remove heat until the thermostat senses that it is 76.
If you lower the temperature setting on the thermostat, it will run until it reaches that setting.
If the unit runs constantly, and is set to 76, setting it to 72 will not make a difference. It will run until it reaches the set point. If the unit is running constantly and not cooling, you have either an undersized unit, or the unit is not functioning properly.

I have 15 years in the HVAC world.
I'll tell you something... 68 degrees with low relative humidity is too darn COLD.
Speaking of relative humidity, that is what a/c is all about. Think of it as a big dehumidifier. Cooling is actually secondary to what we wish to achieve. Remember the saying, " it's not the heat, it's the humidity!" What is actually the point of air conditioning is to reduce the relative humidity in a space so that evaporation of perspiration off your skin can happen more readily. This cools the surface of your skin. Of course, with air conditioning comes the cooling effect as well. Consider it a bonus.
The rule of thumb is to set your temperature no more than 1- degrees F. lower than the outdoor temperature. Consider that 76 degrees with a low relative humidity is far more comfy than even 68 degrees with high relative humidity. Don't believe me? Go down to your basement and then tell me.
Additionally, an a/c unit may not even be able to reach a rediculously low setpoint if it is sized properly for your home. A properly sized unit should run a long time to be able to take out the optimum amount of humidity.
Hope this helps.

If the temperature the air conditioner is lower, then the room will be cooler.
If the room is really big and the air conditioner only has a 8000 or 12000 BTU capacity, the it won't cool anything.

Most people keep their A/C at 68 degrees. Yes, it will make the room/house colder.
It is best to keep the outside doors closed. If there are children/people running in and out, this keeps the A/C from keeping the house/room cold.

That depends on the size of the room and the cooling power of the A/C unit. A given size unit only has so much cooling capacity for a given amount of space.

Yes it would make it cooler but every degree you go up pushes your electric bill up allot higher,
