Not QUITE true. Friction can convert usable energy in useless (or unusable) energy, but energy itself can't be destroyed.
Friction and air resistance cause some of the mechanical energy of an object to change to thermal energy so the mechanical energy of the object is not destroyed. Rather, it is transformed into thermal energy. the total amount of energy always stays the same. ur welcome. you have to give me 5 bucks.
It certainly does; mechanical energy will be wasted due to friction. Otherwise, if you disregard friction, the fact that the total mechanical energy is conserved follows from conservation of energy.

Nope. One of the strongest pillars of Physics is the fact that energy is never destroyed. Energy lost to friction is no longer available to do the job that you happen to need it for, but it's still there, and it shows up as heat.

... friction occurs.
friction
Yes, it can. For instance, if you have friction in the system mechanical energy of the system is not conserved.
Thermal
IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
Heat.
