Output work is always less than input work.
In such a machine, the remaining energy is wasted to friction

No machine is 100% efficient. The amount of work you get out of the machine is always something less than the amount of work you put into it. So you have to put in more work than the job actually requires. It's the price you pay for making the job 'easier' by using the machine to do it.
Yes, usually it will decrease it, since no machine is 100% efficient.Just in case you mean "the amount of work REQUIRED", then of course the machine will INCREASE that.
simple machine.
No, the mechanical advantage is greater than 1. If you input a force of 1 unit you get out a force of 1+ units. However keep in mind that if this were a PERFECT machine the amount of WORK INPUT is EQUAL to the the amount of WORK OUTPUT. Since perfection is not possible, and there are frictional losses this is not possible. Otherwise you could have a perpetual motion machine, which is not yet possible.

Because some of the energy (work) is converted to heat as the parts of the machine rub against each other.

A compound machine is a machine that is made up of more than one simple machine. They they change the amount of force and the direction.
Power is the amount of work a specific machine can do over a period of time. Work is the product of force and the distance an object travels as a result of that force. A more powerful machine can effect changes in velocity of an object more rapidly than a less powerful machine.
6x2x4 = 12x4 = 48 and is less than 50
