Kindly see if these plants could be identified.

To me it seems to be some species of Aralia.

---

No idea, Sir, leaves seem to be compound, but flowers (picture not clear) do not have staminal tube, so not likely Meliaceae. The tree is not armed … so there perishes the probability of  Zanthoxylum rhetsa.

---

I might have guessed wrong, leaves might be simple here. In that case, flowers look like Euonymus spp.

---

The only Euonymus, described in Fl.Br.Ind., comes closer to this one is E. lucidus, but here, in the uploaded pics, leaves are not serrate or even serrulate.

Closest I can go is Ligustrum, but did not find match as per comparative images herein.

---

i would like to suggest a probability, and probability only – nothing more!
