The adjective frei is a versatile word in German with several distinct meanings depending on the context:

Unconstrained/Independent: Describes someone or something that is not under the control, power, or authority of another. It also refers to the state of being free from obligations, duties, or confinement.
Available/Vacant: Used to indicate that something is not occupied, reserved, or in use. For example, a seat on a train or a time slot in a calendar.
Open/Unobstructed: Describes a view or space that is not blocked by objects.
Without charge: Used to mean that something does not cost any money (free of charge).
Released/Exempt: Used in legal or formal contexts to mean that someone or something is released from a burden, tax, or penalty.

Grammar: It is an adjective that can be used attributively (e.g., ein freier Platz - an available seat) or predicatively (e.g., Der Platz ist frei - the seat is available). When used as an adverb, it remains frei.
Origin: The word stems from the Old High German frī, which relates to the concept of being beloved or belonging to a kin/family. Historically, those who belonged to the kin were "free" compared to those who were enslaved or lacked status.
