#1 Arhopala agrata binghami from the lack of costal spots on the forewing and the last costal spot of the post-discal band being very faint. Spots 6 and 7 on the hindwing are also unique. Also, the forewings are much more angular than the hindwings and this contrast gives it a striking appearance which can be seen here

#4 This one's interesting. I could be wrong but i think this has to be Arhopala delta because of the lack of costal spots on the forewing and the fact that it is tailed despite spots 6 and 7 on the hindwing being out of line. The only other species with these characters is A. allata which it is not because that species has more rectangular spots.
