Free agency is a somewhat nebulous term, a blanket statement covering multiple distinct scenarios. Unrestricted free agents can sign with whomever they please, while restricted free agents sign offer sheets which their current teams can match. Contracts may include shortening or lengthening options. Additionally, a handful of players become free agents if they are go unclaimed once amnestied by their teams.

Nevertheless, there have been quite a few unexpected outcomes already, the 10 most surprising of which are conveniently listed for you here.
