⌛ Manila Airport question

Two hours is more than enough time to get thru formalities and get on the next flight between 1 & 2. Done it many times - and another good reason to fly PAL in the Philippines. You can take your luggage trolley from one terminal to another and the distance is maybe 150 metres....If you are transferring to an international flight there are usually 'customer service' reps inside who can get you expedited if you're running late. They often go up and down the lines of waiting passengers to get those most in need processed at the appropriate check-in counters. It's not a great distance between the terminals and no big deal pushing a trolley...easy stroll unless it's pissing down rain.
