Shrubs for ID-4: This plant image was taken in Chennai, South India in the month of July. For ID help plz.

Carissa for sure. Need more  details of the foliage/ fruits for correct ID of the species. C.spinarum is seen in GNP and IIT campus which also look similar to this. As the photos are often deceptive more info is required.

Looks like Carissa spinarum

Pl. find the attached file conatin photo of Carissa carandas.
Location NBNP Garden, Anaikatti, Coimbatore Dist.,

Rather than C.carandas, it appears to be closer to C.congesta which is more popular as an ornamental fruit than the sweeter taste of the former. The fruits are seldom used for hair decoration in Maharashtra by ladies. However, an expert may please confirm the identification.

Nice Catch of ‘Karonda’ used for making Pickles

I think both Carissa carandas and C.congesta are one and the same . Hence, the correct citation could be C.carandas syn. C.congesta. Please see the link for reference : http://www.worldagroforestry.org/sea/products/afdbases/af/asp/SpeciesInfo.asp?SpID=18030

 
Shrub No.2 for ID plz.:   Please help with the ID. All taken in chennai, South India in the month of july.

Please provide a picture with leaves and other information related to this plant such as height, habit, leaf size, shape, etc.

I think it is some species of Carissa (Apocynaceae)
