Multi-device usage offer

Some of the AVG products are for multi (10) devices, such as AVG TuneUp (Multi-Device) and AVG Internet Security (Multi-Device).
My questions are as follows:
Do the other devices need to be owned by me?
Can my relatives/friends use this product?
In case the devices are to be owned by me, what kind of devices I can use them for?
In case I want to use it only on one device, is there any reduction in the subscription fee? 
Thanks and Regards,
Shamprasad
