Main Difference
The main difference between Individual and Entity is that the Individual is a person or a specific object and Entity is a something that exists in the identified universe.
Individual
An individual is that which exists as a distinct entity. Individuality (or self-hood) is the state or quality of being an individual; particularly of being a person separate from other people and possessing their own needs or goals, rights and responsibilities. The exact definition of an individual is important in the fields of biology, law, and philosophy.
From the 15th century and earlier (and also today within the fields of statistics and metaphysics) individual meant “indivisible”, typically describing any numerically singular thing, but sometimes meaning “a person”. From the 17th century on, individual indicates separateness, as in individualism.Although individuality and individualism are commonly considered to mature with age/time and experience/wealth, a sane adult human being is usually considered by the state as an “individual person” in law, even if the person denies individual culpability (“I followed instructions”). An individual person is accountable for their actions/decisions/instructions, subject to prosecution in both national and international law, from the time that they have reached age of majority, often though not always more or less coinciding with the granting of voting rights, tax and military duties/ individual right to bear arms (protected only under certain constitutions). In line with hierarchy, ultimate individual human reward for success and responsibility for failure is nonetheless found at the top of human society
Entity
An entity is anything that claims independent existence (as opposed to merely being part of a whole), whether as a subject or as an object, actually or potentially, concretely or abstractly.
The term is broad in scope and may refer to animals; natural features like mountains; inanimate objects like tables; abstractions like numbers or sets; human contrivances like laws, corporations and academic disciplines; or supernatural beings like Gods and spirits.
The adjectival form is entitative and refers to something considered in its own right.
