Whilst we wait for Seow's sharp eyes to nail these two, I'll give it a shot.
The first one matches the Dark Caerulean (
Jamides bochus nabonassar)'s markings. Go thru the checklist and compare this one.
The 2nd one doesn't exactly match the samples, but I'd say it's closest to the Vinous Oakblue (
Arhopala athada athada) from the hindwing and forewing markings.
