How to set the landmarks (Red coloured points) as given in the image 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:
