The definite and indefinite articles are all determiners.

There are four demonstrative determiners in English and they are: this, that, these and those
Note that demonstrative determiners can also be used as demonstrative pronouns. When they are used as determiners they are followed by the nouns they modify. Compare:
This is my camera. (Demonstrative used as a pronoun, subject of the verb is)
This camera is mine. (Demonstrative used as a determiner modifying the noun camera.)
Possessive adjectives - my, your, his, her, its, our, your, their - modify the noun following it in order to show possession.
Possessive determiners are different from possessive pronouns - mine, his, hers, yours, ours, their.
Compare:
This is my house. (my is a possessive determiner. It is followed by the noun house which it modifies)
Is that car yours? (yours is a possessive pronoun. It is not followed by a noun.)
Quantifiers are followed by nouns which they modify. Examples of quantifiers include:
some, any, few, little, more, much, many, each, every, both, all, enough, half, little, whole, less etc.
Quantifiers are commonly used before either countable or uncountable nouns.
He knows more people than his wife.
Little knowledge is a dangerous thing

Numbers are cardinal (one, two, three, etc) and ordinal (first, second, third, etc). Cardinal numbers are adjectives that indicate quantity (There are five apples on the table), and ordinal numbers indicate rank or order (This is the first time for me on a plane).
There are five apples on the table
The words all, both, half, each, every, either and neither are known as distributives.
