Thank you.
AD was ringed on 17-Apr-2022, seen in Oct-2022 by you, and then in Mar-2023 by another bird watcher at Mai Po. This is the 3rd sighting.
DV was ringed on 31-Mar-2017. It was reported in spring 2019 and 2021 at Mai Po and Shenzhen Futian. Great to see it stop-over here again this year.
TT was just ringed on 7-Apr-2023. This is the 1st sighting.
For the last photo, I think both RN, PN, HN are possible. Sorry that I can't confirm. All 3 are ringed in Apr-2022.
