It seems most of the photos have similar treatments having a vintage and faded look. I tried to play around with curves and saturation but cant seem to get it. Anyone would like to share some techniques on this? Thanks!!

try color balance and/or hue

Search for cross processing in Photoshop

Selectively shifting hue/sat adjustment layers and limiting them to some particular colours sometimes can give a cross processed look... but a Google search should yield some tutorials about it.
