How can I set the landmarks for different facial components like (eyebrow, eye, nose & lips) on a front posed face image (neutral emotion) and how to track the points of those fixed landmarks on the front posed face image of (different emotions) ?

We can't really help with long complicated algorithm development questions like that. What you've asked for is no 5-minute answer -- people have been working on that for years. You can find their algorithms by looking up the papers they've published on them, which are cited here:

Pick a paper then code it up.

Hi Swaminathan,

You can use vision.CascadeObjectDetector in the Computer Vision System Toolbox to detect faces, eyes, noses, and mouths. You can also use functions such as detectHarrisFeatures or detectFastFeatures to detect corners inside those regions. Finally, you can use vision.PointTracker to track corners across video frames.

Webcam support is only available in base MATLAB R2014b or later. You can use Image Acquision Toolbox to capture video instead, or read video from a file.
