I have a flight on June 19 MNL- BKK

MNL- HKG is on first class and my connecting flight HKG- BKK is a 2- class configuration only. I know I can access manila's F- class lounge , am I able to access the HKG F- class lounge as well or the C- class lounge? I am aware that i will be given an invitation lounge in Manila for the manila and hkg lounge already or I will be given 2 separate lounge invitation?
