Using software RAID only

Is it possible to start with a 2TB disk full of data and safely add it to a RAID 1 array?

Is it then possible to add a third disk and migrate the RAID 1 array into a RAID 5 array?

OR

Is it possible to start with a 2 disk degraded RAID 5 array and then add the third disk later to create a health RAID 5 array?

Backstory:

I wish to migrate from a 2 disk NAS (RAID 1) to a 3 disk NAS and only purchase one new disk in doing so
