There appear to be two species & perhaps several individuals.

Pix 2, 3, 4, 5, & 6 appear to be Euploea doubledayi .(Probably E. doubledayi occur in Penang after all.)

The 2nd pic here shows a narrow brand & the HW with longer stripe-like spots.
The dull blue-black FW sheen indicate it should be E. doubledayii.
The UpF of E. eyndhovii is dark brown.

Pix 1, 7, 8, 9, 10, & 11.should be Euploea algea.
The HW submarginal spots are shorter bars, longest at the tornus & tapers upwards.
The upperside have a deep dark blue brilliance.

The male brand is broad & long.

Other similar species have the HW submarginal spots more uniform in size.

Dr Seow, Thanks for all the detailed ids. Appreciate it

For #1 Euploea, I believe all the photos are of the same butterfly which I spotted outside a shopping mall - where four of these ficus-looking trees (I dont know how to id tree) are planted. The butterfly would fly off and then land on another part of the tree or another tree when I approached too close. All photos were still shots of videos that I took - all within 10 minutes.I did not see another Euploea or other butterfly when I was there that I am aware of.
