Narrative: I was working handoff position and was not very busy. My radar controller and I were maybe talking to 5 airplanes in the R2508 [restricted area] complex. There was a supervisor working the adjacent sector radar position. We noticed that controller was getting busy and heard them call to coordinate for a whiskey alert about a VFR entering R2515 airspace without a clearance and being vectored out. I mentioned that the controller was getting busy so we monitored the position to watch and see if we could assist from our airspace. I noticed Aircraft X on a vector to an ILS approach from the west; which we typically don't do with IFR aircraft because of the proximity to R2515. I noticed Aircraft X was within 3 miles of the restricted airspace; and it was already too late to warn the controller. With the controller being a supervisor; I assumed he was reporting the incident. But when I relieved the controller-in-charge; I noticed there was nothing filed for the incident; so I am unsure if the supervisor reported it.I have discussed; with this supervisor specifically; the need for supervisors to not work heavier traffic due to the lack of proficiency. Hopefully; this individual will see the error and realize supervisors should leave the heavier traffic to people who work traffic all the time; not just 8 hours a month.


Second narrative: Aircraft X was at 20000 feet and descending to 14000 feet less than 60 miles from the airport. He was coming into my airspace from the northwest and descending to 14000 feet. There was a line of three aircraft from the east also descending to 14000 feet. ARTCC sector did not coordinate anything and I didn't take the hand off until ARTCC had descended Aircraft Y from the east to 14000 feet. Aircraft X got trapped on top of Aircraft Y and was 20 miles west of the airport at 15000 feet. Once I was talking to him I descended him to 6000 feet and assigned him a heading. He reported the field in sight and I cleared him for the visual approach. I had to turn him to keep him away from the restricted area. A couple of minutes later I noticed Aircraft Z who had entered R2515. I turned Aircraft Z out to the south and my Radar Assist coordinated the Military Controlling Agency. I was getting proficiency and had airplanes coming from four different directions all descending to the same altitude. Arrivals are often high regardless of the direction they come from. Arrivals from the northwest should be coordinated to cross at 13000 feet. That would allow us to get them down below the main flow of arrivals from the east.


Synopsis: An ATC Supervisor was working a sector around Restricted Airspace. The Controller/Supervisor got busy and did not notice a VFR aircraft they were working enter the Restricted Airspace. An arriving air carrier was vectored for its descent to land and got within three miles of the Restricted Airspace boundary. Required separation from Restricted Airspace boundary is 3 miles or greater.
