"Separation," in terms of aircraft, is the minimum distance, both laterally and vertically, permitted in order to be considered "safe."
In other words, "separation" is the distance between aircraft in all directions. If a flight is maneuvered for "separation," it is simply being turned in a direction that puts more distance between it and other aircraft.
When an RA is issued, pilots are expected to respond immediately to the RA unless doing so would jeopardize the safe operation of the flight. This means that aircraft will at times have to maneuver contrary to ATC instructions or disregard ATC instructions. In these cases, the controller is no longer responsible for separation of the aircraft involved in the RA until the conflict is terminated.
Immediately but there is a danger of getting into "bad air". The separation is not controlled in 'minutes' but in distance between the two aircraft. Here are the rules from pilot training:* Category Ilight-weight single-engine propeller driven aircraft * Category IIlight-weight twin-engine aircraft weighing 12,500 pounds or less * Category IIIeverything else including high performance single-engine propeller air-planes, large multi-engine propeller aircraft and all turbine powered aircraft The FAA separation regulations also specify that departing aircraft may not take off from a runway unless: * A landing aircraft has taxied clear of the runway, or * A departing aircraft is airborne and is clear of the departure end of the runway or * A departing aircraft has turned away from the departing runway But the regulations also say that the following aircraft can depart: * If the take-off separation is 3,000 feet and both aircraft are Category I * If a Category II aircraft departs before a Category I aircraft * If a Category II aircraft takes off after a Category I aircraft * If both aircraft are Category II aircraft and the separation distance is 4,500 feet * If either aircraft is a Category III aircraft and the separation distance is 6,000 feet from a virtualskies.arc.nasa.gov tutorial (see link)

When aircraft are flying it is important that they do not fly into one another. To help avoid this flight paths for aircraft going in opposite directions are separated one form another and each aircraft is separated from those above, below, behind and in front by a 'box' of air this is the separation of air craft.

It depends what type of aircraft AF1 is. But the separation is the same as for other aircraft, 1000ft vertical, 3 miles lateral. If AF1 is a "heavy" jet, then another aircraft would have to be 4 or 5 miles behind it, depending on the weight category of the following aircraft. AF1 gets more room ahead of it into and out of airports due to the requirement of runway sweeps before it lands and takes-off.
