How to skip a page in a ViewPager depending on certain condition , swiping forward or backward , knowing that i don't know the the position of these pages .

Yes you can. Normally what happens is that you will create a ViewPager and set an adapter to it. This adapter has the getItem(position) method. You override this method and for each position you will spit out a Fragment. This is the place where you need to check your condition and send out different Fragment.
However if you are going to reduce the number of items, you also need to adapt the getCount() to suit your needs.
