Hint: A possessive noun is a noun that owns something—that is, it owns something. In most cases, a possessive noun is formed by adding an apostrophe +s to the noun, or if the noun is plural and already ends in s, only an apostrophe needs to be added.

Complete answer:
If the singular noun ends in s or not, the possessive of a singular noun is formed by adding an apostrophe and the letter s. When a plural noun ends in s, the possessive is formed by adding only an apostrophe, and when it ends in a letter other than s, it is formed by adding both an apostrophe and an s.
Adding 's' to a phrase usually makes it possessive. This works for all singular terms; however, the majority of plural words would, unsurprisingly, end in 's'. In this case, simply add an apostrophe after the 's' (for example, autumns = autumns'). The only exception in your list was 'kids', as this has an irregular plural – children. Here ‘s’ is added after children.

The following table shows the singular and plural possessive form of the above-mentioned words.


Note: i) Add 's’ to most singular nouns to make the possessive. Example: It is Reenu’s pencil.
ii) After the s, add the apostrophe to form the possessive of most plural nouns.
