Three missing registration numbers

…so as much as I try to avoid not including aircraft numbers when I photograph, it does happen at times and I have three planes I’d want to know numbers for if anyone is willing to assist – here’s the information I have:

LAX arrival – Singapore Airlines – Airbus A380-841 – 2016, April 6 – 12:48pm (approx. touchdown)

LAX arrival – Lufthansa – Airbus A380-841 – 2016, April 17 – 12:43pm (approx. touchdown)

LAX arrival – American Airlines – Boeing 777 – 2016, November 27 – 3:47pm (approx. touchdown)

Very grateful for help with this – and Thanks in advance,
