The one at the bottom looks like a Rosefinch, possibly a Common Rosefinch, Carpodacus erythrinus.

This is probably the Common Rosefinch. Old male, in post-breeding plumage.

Bird of the first pictures I can try to determine later how to get back to work in the museum.

For the first picture Common Babbler (Turdoides caudatus) might be a good place to start. I'm not familiar with the group and there may be other species that look similar.

first picture is yellow-billed babbler or white-headed babbler (Turdoides affinis)

Yellow-billed babbler or white-headed babbler (Turdoides affinis)

Common rosefinch (Carpodacus erythrinus) or scarlet rosefinch

Most probably the jungle babbler (Turdoides striata or orientalis) normally found in large gardens and fruit orchids, especially Mango cultivation of South Asia

Dear Armando,

 1. Jungle Babbler (Turdoides striata)

 2. Most probably Common Rosefinch (Carpodacus erythrinus)

Best,

Tharindu.

Image 1 is the Jungle Babbler (Turdoides striata): separated from T.affinis by less mottled throat and distribution (New Delhi) the second image Streaked Rosefinch (Carpodacus rubicilloides): Notice the darker head and which is absent in Common Rosefinch, also darker centers to the wing feathers vs lighter on C. rubicilla

Thanks Asif, Armando
