If you buy 1 licence you will receive one licence key and can use this on 1 device.
If you buy 5 licences you will you will receive one licence key and can use this on up-to 5 devices.
Each licence key has a number of activation slots based on the number of licenses you have bought. When activating a device an activation slot is reserved from the total number of slots.
You have one licence key with 5 activation slots, 4 activation slots are in use and you activate another device, there are now 0 remaining slots. If you wish to activate on another device you must either de-activate a device or buy another licence. More information on activating and de-activating licenses can be found here.
