等(など)Such as, Things like, Etc., And so on

Both なんか・なんて and など can be used to give examples, like '(A) and so on' or 'things like (A)', but they differ in nuance and formality. など is neutral and used in both speech and writing. なんか・なんて are more casual and often carry a dismissive or belittling tone, like '(A) and whatever' or 'unimportant things like (A)'.

だの and など are similar in that both are used to list examples. They differ in that だの will often explicitly list multiple examples, while など can be used with a singular example to suggest 'and things like that'. Also だの often is used in statements with a negative implication, while など is more neutral and has no such limitations.

といった and など both give examples, but differ in usage. といった appears in the form AといったB, meaning '(B) such as (A),' e.g. サッカーといったスポーツ ('sports like soccer'). など can be used similarly as AなどのB, but also stands alone, e.g. サッカーなどが好き ('I like soccer and similar things.').

など and とか～とか both list examples, but differ in nuance and structure. など usually follows a single noun or ends a list, implying the items are representative, like '(A) and so on' or 'things like (A).' とか～とか follows each noun and emphasizes specific, individual examples, like '(A) and (B), for example'.
