1. Celatoxia marginata.Female.
Among the genera with a white dot at the antennal tip include Celastrina, Udara ,Celatoxia, Lestranicus & Callenya.

C. lavendualris have spots with white halos, while C. argiolus have small spots.

This one have heavy postdiscal spots so most of the other genera can be excluded.

Oreolyce archena is very similar but the antenna does not have a white dot & HW has an extra spot at the base of space 1b.

This leave C. marginata which has heavy postdiscal markings,

2. Nacaduba beroe male; Note the costal spot above the mid cell band is missing (similar to I. helicon)

Nymphalinae:

Kallima inachus siamensis





Junonia iphita (Chocolate Pansy)



Symbrenthia lilaea (Common Jester)

Yes they are both Kallima inachus siamensis.

They can be quite confusing.
It is impossible to ID from the underside pattern, as it is so variable.

K. inachus; FW apex with a small pointed tip & HW tail longer.
HW tail nearly as long as the lower distal margin from vein 2 (where it is strongly angled) to the the tornus.
Upperside orange band inner border with a series of deep well-defined indentations.

K. limborgi FW apex in the male not produced to a tip but does so in the female.
HW tail shorter , shorter than the lower distal margin from vein 2 to tornus.
Upperside with the orange inner border irregular, without sharply defined indentations. Correction: Can also have well-defined indentations.
