Hello Hetal,
While the other members have given very valuable & practical suggestions based on their experiences, I would like to highlight a basic human factor: by nature, human beings are wired to work without breaks for longer durations in the daytime rather than during night-time. So unless you break the monotony of the work each of them does--either by way of some leisure/recreation activities during the night shifts OR switch the work from one activity to another--like the Saying goes: "Relaxation is nothing but change of work". Maybe you can plan role changes/rotation among the team members. Just give this a thought.
Coming to your query ".....employees are allowed to work at same time while they are working with us", many companies actually bar such avocations by the employees as this has the scope to create a loss or diffusion of focus towards the company's work by the employee(s).
However, you mentioned this reg one employee--is this found with ONLY one or many employees? If not, you would need to figure-out the reason(s) of the others.
Like all the members suggested, a Full-team meeting could give you some leads [obviously you can't expect many employees to clearly state the actual reasons for sleeping on duty, unless they are very honest by nature]--this also depends on YOUR body-language; IF you are PERCEIVED as being probing for taking any harsh/punitive measures, none will come-out with the ACTUAL reasons. Hope you get the point.
You can then pursue/probe further to get to the truth & then begin implementing corrective measures.
