Indefinite : are those referring to one or more unspecified objects, beings or places. They are
called indefinite simply because they do not indicate the
exact object, being or place to which they refer.

Somebody explain what is going on!
Everyone believes she is amazing.
No one wants to hear you.
Either choice has its advantages.
Relative : are used to refer to nouns previously mentioned,
whether they are people, places, things, animals or ideas.
Relative pronouns can be used to join two sentences. Most
common are: which, that, whose, whoever, whomever, who
and whom.
Examples

Lasagna, which I eat once a month, is my favorite food.
Where did you buy the skirt that you wore last Monday?
Reflexive : is a type of pronoun that is preceded by the adverb, adjective, pronoun or noun to
which it refers, so long as that antecedent is located within the same clause.

Intensive : a pronoun that ends in self or selves and places emphasis on its antecedent by
referring back to another noun or pronoun used earlier in the sentence.
