Photo at Sr.No. 6 Looks as Polygonum hydropiper- Jal marich.
The plant uploaded is Persicaria hydropiper variety elagans
To me appears more close to Persicaria glabra
Not P.glabra.. I'll get back to you soon.
to me, it looks like Polygonum hydropiper, The leaf juice is pungent and strong-smelling. Crushed leaves are put into the deep pond inhabiting fish which forces the fish to come out from their hiding as the plant juice is irritating to the fish eyes Forms patches in moist, boggy places.
Thanks, … But looks different from Persicaria hydropiper as per images and details herein.
Though the plant P.glabra grow\s Also grows under a similar environmental niche,, the nodes have glabrous scales with rough hairy sheath enclosing the nodes.
Find below images of a population of Polygonum hydropiper from Dist. Mandi, Himachal Pradesh.
Thanks for sharing the photographs Sir! But somehow it doesn't look like P. hydropiper to me. Could you please share some close shots?
The Photograph send by ... is Persicaria serulata
To me appears more close to Persicaria glabra 
With this photograph, it is difficult for me to confirm the ID. P. hydropiper has many allied species and they all look alike. Close up of the inflorescence and ochrea is required.

Persicaria ....??? 

Most probably Persicaria hydropiper (L.) Delabre
Many allied species of the same are known. Therefore, we'll need more photographs showing the floral characters to confirm the ID.
Pl. see all the high resolution images at SK 2841 11 November 2020 

Yes, I saw that. Can't see the open flowers there. Therefore, suggested the tentative ID.
