1a. https://www.inaturalist.org/observations/277224580
1b. https://www.inaturalist.org/observations/276835207

Both are Appias indra plana.

There is a lack of clarity in 1a which makes the ID more difficult.
The FW border *see thru) is much as in A. indra
Thw FW apex shows hint of white and the HW base hint of yellow.
1b is more specific with the paler apical area sharply contrasted with white shading at boundary with the black dical band,

Appias indra plana.

Phrissura ( or as Udaiana) cynis
FW apex graded brown, no white shadings, hW costal base not yellow-tinged.

2b. https://www.inaturalist.org/observations/277224575

Subapical spot8 is reduced to half so there is a possibility it may be P. juno.
but it could just as well be P. omaha.

P. juno.
Subapical spot much reduced ,often absent.
abdominalend lightly dark banded.
Underside lightly dark-shaded.

These are typical Polytremis lubricans.
FW spots are dfistinctly yellow, Fw cellspots two ,often conjoined.
Spot 2 large, ovoid in the male, more rectangular in the female.

5. https://www.inaturalist.org/observations/277224567
Probably correct as Korothaialos sindu.
The conical palpi and orange band reaching costa exclude K. rubecula female.

6. https://www.inaturalist.org/observations/277183746
Notocrypta feisthamelii.
The extra spots on the FW including 3 subapical spots in a straighy line.

They all should be Udara dilecta.

The Udara species are divided into two main group based on the presence or absent of the submarginal lunulate line/spots.
Udara dilecta belongs to the group with submaarginal lunules.
They include U. dilecta, placidula, rona, cyma and similar species as celastrina lavendularis, and Callenya lenya.

Udara dilecta is unique in that HW postdiscal spot 7 is no darker than the rest of the postdiscal spots on both wings.
In all other species, HW spot 7 is darker than the other postdiscal spots & often black.

Udara dlecta.
HW spot 7 no darker than the other postdiscal spots.

8. https://www.inaturalist.org/observations/275752657
Likely Hasora myra.
Too blur and dark.

Three similar species.
1. Hasora myra.
HW tornal area not darken .

https://www.gbif.org/occurrence/2847176188
https://wingscales.com/media/2400/6657-1-af649.jpg

The other two have the HW tornus darken.
H. lizetta more ochreous.

https://www.gbif.org/occurrence/4868026200

H. zoma larger and darker.

9.https://www.inaturalist.org/observations/276823429
Too blur. Probably B. harisa.

10. https://www.inaturalist.org/observations/275752611
Probably Polyura paulettae.
Reviw later.

11. https://www.inaturalist.org/observations/276154697
Likely Curetis bulis.
The upperside shows large orange areas but thatis likely to be due to motion blur.
Last ic is the clearest.
HW submarginal spots 6 & 7 in line.
Postdiscal spot 7 large & crescentic, spot 6 small & tuck under it.
