As I said 7 lights, 4 on the front and 1 for each man door which is 3. What I am looking for is, if I walk up to any side of the garage at night with motion detection added on I want all 7 lights to go on. Each light will have its own motion detection unit added on, and connected to the rest.
Or would a single photo cell wired across all 7 so at nite the garage lites up. Will be using LEDs in each of the single bulb exterior lights. Can this be done to have all the lights turn on with only 1 motion detection unit added to one light or all 7 lights? Even though all lights would have their own mini motion detection unit added and mounted 3 to 4 feet lower than the light fixture.

It sounds like the switch is at the end of the electrical run; the white wire that's connected to the black wires is carrying current to the switch, then the black wire coming back from the switch is connected to the light:
You need to connect the black wire for the new outlet to the black wire going to the light, not the cluster of other black wires; all the neutrals and grounds should be OK as they are.
While you've got the electrical box open, does the white wire connected to the black wires have black electrical tape wrapped around it? If not, it should; this will indicate that it can carry live.
Since the red wire is already being used for the outlets, you'll need to run a pair of 3 wire cables from the existing switch box to the location in the garage where you want these light switches.
This is what you'll likely have to do:

Yes, you can crossover motion detectors if you set it up properly. You would use discrete motion sensors and lights, not combo light-sensor units. If you're married to the idea of combo units, you will need to "hack" them, which is off-topic here.
All motion sensors have day/night detection, and will not activate in daylight.
So to wire this, you must
You can use /3 cable for this.
