The package name (what you have here) contains elements that identify the company providing it and elements that tell you what it is. 'Qualcomm' are the manufacturers of the system chips used by a large fraction of phones worldwide, and 'QTI' is 'Qualcomm Technologies Inc'. So the 'com.qualcomm.qti' bit is just saying 'this is qualcomm software'.
So you've 2 apps from the manufacturer of the key part of the system hardware (including the radio interface). One is called 'network setting' and the other is called 'call feature settings'. So they are system apps related to the networks and calling features. I suggest that they are nothing you should worry about and also nothing you should try to interfere with.
