No, due to the fact machines loose energy due to heat/thermal energy. you will always loose some amount of energy.

Why do levers have a greater mechanical efficiency than simple machines?

The transmission lever is very simple and there is no friction.

If the output work of a simple machine equals the input work the machine is said to have efficiency.?

In that case, the efficiency is said to be 1 - or equivalently, 100%.

A simple machine requires this in order to operate?

The mechanical advantage of a compound machine is the multiple of the separate mechanical advantages of each simple machine. The efficiency of the compound machine is also the multiple of the separate efficiencies of each simple machine. So the work in to the first machine multiplied by all of the simple machine efficiencies gives you the work out of the last machine

Levers have a greater mechanical efficiency that other simple machines because?

They have to overcome less friction
