Difficult to identify plants without flowers and fruits. It may be Cucurbitaceae/ Convolvulaceae plant.

Cucurbitaceae sp.

Dear Rashid

It is a member of Cucurbitaceae and hope quite allied to the genus Momordica.

Sunit Mitra

I think this belongs to Cucurbitaceae family

Sunit Mitra is right. It may be Momordica genus 

Dear Rishad 1st one is Cucurbitaceae member. It may be Memordica sps. 2nd one is Convolulaceae member.

I fully agree with the views of Aravind Singh, The second one based on the morphology of tendril may come under convolvulaceae.

Rishad,

Cut a fresh stem, squeeze it in your fingers and look at the area where the cut was made. Many Convolvulaceae tend to have milky (white) latex -not in copious, will require some squeezing with your fingers.  

Also, check if the veins of the leaf finish at the border of the leaf in glandular structures. This is common in Cucurbitaceae.

Let us know what it was.
