Neha ji I have a feeling that if taller plant with 5 pairs of leaflets in your third photograph is different, the rest of plants with four pairs of leaflets could well be Senna uniflora in which plants have 3-5 pairs of leaflets and glands in lower two or all pairs of leaflets and the glands stalked. You may also look for pods which are very distinctive. Please go through this paper.
