Explanation:

Only two

Lion-tailed Macaque - They are primarily diurnal, meaning they are most active during the day.

Malabar Civet - They are nocturnal, most active after sunset.

Sambar Deer - While Sambar deer can be active during different parts of the day, they are largely crepuscular to nocturnal. They are most active during the early morning and evening.

So, Malabar Civet and Sambar Deer are the ones that are generally nocturnal or most active after sunset, making the answer "Only two".
