HKIA is very efficient.
Her baggage will be checked through and she will have her HKG-JFK boarding pass. There will be someone waiting at the end of the jetway to point her to the gate. She will not be the only one taking connecting flights, as there are many at that time of the morning, so it will be highly likely that it will arrive on time and there will be no problems.
The worst bit will get getting to MNL for the 0630 departure - too early for some.
