Can I turn find my iPhone from another iPhone with same account

Sorry, no. Find My iPhone cannot be turned on remotely. See the "If Find My [device] isn't turned on on your missing device" section of If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support for some other things that you may want to do.

No.

Find My Phone can only be enabled with the device in your hands.
