For the first picture, a closeup picture with preferably flowers or fruits is needed for some guess.

The leafy plant seen in the Second picture is Blepharis madraspatensis of Acanthaceae. But the tendriled stem seen may be of some Vitaceae plant.

The third picture seems to be Cissus vitiginea of Vitaceae

Hello there Jayaram

Before answering I will need to know whether these images are all from the same plant with aromatic leaves and the location where it was photographed.

The three pictures show different plants: the first a small tree surrounded by a climber, neither recognisable; the second sterile twigs with leaves whorled by 4, unknown to me; the third a fruiting liana with subsessile ternate leaves and some tendrils. The latter belongs to Vitaceae, perhaps a Cissus species.

The second photo is Blepharis maderaspatensis (L.) B.Heyne ex Roth (Acanthaceae) and third Photo looks like a Cyphostemma setosum (Roxb.) Alston (vitaceae)

Dear All,

Thanks for the kind help.

First Image, is a single tree, i will update a fruit and flower image later.

Second image : Blepharis maderaspatensis is correct.

Third image: amazingly close enough to Cyphostemma setosum. but, it must be Cissus rotundifolia.

Ms Daniela C Zappi,  the first image tree flower and leaves very aromatic and attractive. all images photographed last week southern india. 

Thanks and regards

Jayaram

I think the last picture with red fruits is Cyphostemma quintell; which belongs to the Order Vitales; family Vitacea.

@ Yohannes Beyene Mekonnen it is Cissus rotundifolia

The multi-stemmed small tree in image 2 seems to be Cordia monoica Roxb. of Boraginaceae family.
