Can I merge my iPod touch and my iPhone

Not sure what "merge his iPod5 touch onto his iPhone 5s" means.

He can sync everything to the new iphone.

Maybe this:

iOS: Transferring information from your current iPhone, iPad, or iPod touch to a new device

No it is not possible to trasnfer data from ipod to iphone directly, in order to ipod to iphone or vice versa you must have to connect your apple device to your MacBook. After connecting the device the MacBook sync your device to organiize its and enable to trasnfer files to iPhone and other mutimedia device.

Use an application to easily transfer files.
Drag and drop files iPod to iPhone or vice versa.
