Bhikshu = beggar, monk, male member of the Buddhist sangha who has entered homelessness and received full ordination (Sanskrit) / bhikku

I have no clue as to who a 'Dhutavira' is.

Dhuta = ascetic
As in [At that time the Bodhisattva Heavenly Imperative asked the venerable Mahakasyapa, "You are of senior years and have long abided as foremost in the cultivation of the dharma of twelve dhuta (ascetic) practices. How is it that you are unable to remain still in your seat?"]

Vira = Hero/ Heroine

So Dhutavira could be put together as "ascetic hero"

Bhikshu Dhutavira = could best be put together as 'Ascetic monk'

All this is more sanskrit than hindi.
