1.https://www.inaturalist.org/observations/265802681

I am afraid the underside shot is very poor.
However, the postdiscla band is parallel to the margin. & composed of linear marks without shadings.
The upperside rules out possibilities like C. sperthis.
Most of the other also have the postdiscal band composed of shaded lunules (including sperthis)

The most likely ID is c. insularis.
This normally have straighter postdiscal band.
There seem no other possibility.

C. insularis.
https://www.gbif.org/occurrence/2847201292
https://www.gbif.org/occurrence/2847199206
https://thaibutterflies.com/Butterflies/curetis-insularis/

C. freda have the band straighter still, & partly shaded.
https://thaibutterflies.com/Butterflies/curetis-freda/

Others with band parallel to margin have mostly irregular band on the HW.
C. tagallca. (C. saronis is similar.)
https://www.gbif.org/occurrence/2847201238
C. regula have the band heavily shaded & lunulate.
https://www.gbif.org/occurrence/2847199187



2. https://www.inaturalist.org/observations/265802672
I think you have two species mixed up here.

Images 1, 2, & 5 is the same as Fieldshot 1 above & is probably C. insularis.

Images 3, 4, & 6 ,the upperside is that of C. bulis or sperthis.



3.https://www.inaturalist.org/observations/265802669
The band is straight & also shaded on the inside.
Should be C. freda.

https://thaibutterflies.com/Butterflies/curetis-freda/



4. https://www.inaturalist.org/observations/265802802
The UnF band is oblique. Upperside is that of C. bulis/sperthis.
Male Curetis bulis.

[Psyche]

5.https://www.inaturalist.org/observations/265800925
the postdiscal band is composed of linear dashes without shading.
Male C. insularis.


6. https://www.inaturalist.org/observations/265800924
The unf band is oblique, composed of shaded lunules.
Ground colour is speckled with black dots.
The pattern is that for C.. bulis, santana & felderi.
Hw with postdiscal spot 6 & 7 in line & this suggest C. santana



7. https://www.inaturalist.org/observations/266068725
The 1st pic is hard to judge.
The 4th pic show HW postdiscsl spot 6 & 7 in line & submarginal spot 6 & 7 out of line.
This is as for C. santana.
The upperside also is indicative of c. santana.



8. https://www.inaturalist.org/observations/265800923
Curetis sperthis,
FW band composed of shaded lunules 7 parallel to margin.
Underside with black dots & legs banded orange.
All features are as for C. sperthis.

9.https://www.inaturalist.org/observations/265802784
There is no way to tell what this should be, celeno or pura but the straighter fW margin suggest pura.


10. https://www.inaturalist.org/observations/265802793
Jamides pura male.

The black cilia can be seen on the hW easily. Going upwards to the FW, the same cilia can be seen.
The opposits FW's black cilia can also be seen.
In between the two is a line of pale blue ,indicating the FW is blue to the margin.

J. pura .
Male uniform blue to the margin.
(Those form with the FW margin composed of dots are best left alone. They do not occur in P. Malaysia
and may have an element of doubt in the ID.)
Males.
https://www.gbif.org/occurrence/2847200485
https://www.gbif.org/occurrence/2847200487
Female wing slightly translucent with underside markings faintly visible.
https://www.gbif.org/occurrence/2847200476


11. https://www.inaturalist.org/observations/265802781
Male J. pura.
The upperside shot shows the left FW & clearly the margin have no black border.



12. https://www.inaturalist.org/observations/265802770
The very round FW show this female is best left as J. celeno.
(In fieldshot identification always defer to the commonest species if there is no indication it could be eitherwise.)

[Psyche]

13. https://www.inaturalist.org/observations/265802789
Arhopala selta male.
Three criteria are needed .

1. It is a member of the cleander group
a. FW band not or partially dislocared at vein 4; spot 4 never shifted out.
b. HW postdiscal band is fully dislocated at vein 2.
c. HW postdiscal spot 7 is directly atop spot 6.
( These constitute the cleander group;. A selta is a member of the smaller alea subgroup.)

2. HW spot 6 is large & widely overlaps the cellend bar.
3. FW margin is convex.
28779
Typical male.
https://thaibutterflies.com/Butterflies/arhopala-selta/



14. https://www.inaturalist.org/observations/266078088
Despite the very oblique ,HW spot 6 is large & overlapping the cellend bar indicating it is another A. selta.



15.https://www.inaturalist.org/observations/265802688
Too blur.

[Psyche]

Two similar species can be very confusing.
They are medium, tailless, with a tooth at vein 2.
They normally lacks a white cilial at the tornus but sometimes it is weakly resent.

Arhopala amphimuta .Commoner.
UnH 'V' spot well-shaped with equal arms.
UnH postdiscal spots 3, 4, 5,& 6 of equal size & aligned as a band above the V spot.
Male upperside with blue to the margin ,female less.

https://www.gbif.org/occurrence/2847202533
https://www.gbif.org/occurrence/2847202529


Arhopala major.
In Singapore much the commoner of the two.
Male upperside with broad black border, the female more so.
UnH postdiscal spot 3, 4, 5, & 6 of unequal size & often dislocated.
V spot mishapen with unequal arms.
Singapore.

Arhopala amphimuta.
UnH v spot well-shaped & postdiscal band above it well-formed.


17. https://www.inaturalist.org/observations/264051164
A. amphimuta.


18. https://www.inaturalist.org/observations/264051158
Markings unclear.
Rounded HW, no tooth Likely subgroup of small species eg A zyida, stubsii etc.


19. https://www.inaturalist.org/observations/264051157
Female Arhopala amphimuta.


20. https://www.inaturalist.org/observations/264051148
Not clear enough. Amphimuta group, subgroup amphimuta.
Probably A. amphimuta itself.
