とかAmong other things, For example, Such as

なんか・なんて and とか～とか both give examples, but differ in tone and usage. なんか・なんて usually follows a single noun to imply 'things like (A)', often with a dismissive or belittling nuance. とか～とか is used after each item in a list and simply means 'things like (A), (B), and so forth' without any negative implication.

While both やら～やら and とか～とか list examples, they differ in nuance. やら～やら often has an uncertain tone or a presents contradictory possibilities, e.g. 行くのやら行かないのやら ('whether he's going or not'). とか is more neutral and casual, simply listing examples without a strong nuance of uncertainty.

Both たり～たりする and とか～とか are used to give examples of actions, similar to the English '(doing) things like A and B.' The key difference is how they attach to words. たり is made by adding り to the た (past tense) of a verb, while とか follows the dictionary form. Also, とか can follow nouns directly, while たり requires だ to become だったり.

たとえば and とか～とか both introduce examples, but differ in usage. たとえば comes at the start of a sentence or clause, like 'for example'. In contrast, とか～とか is used to list multiple items and follows each noun. Because they differ in function, they can be used together in the same sentence, e.g. たとえば本とか雑誌とか ('For example, things like books, magazines, and so forth.').

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'.

し～し and とか～とか both list things, but with a different nuance. し～し lists reasons or causes, like 'because of things like (A) and (B)'. とか～とか simply lists items without implying they are a cause for something else, i.e. 'things like (A), (B), and so forth'. Also, とか～とか is very casual, while し～し will be found in both speech and writing.

While both ～なり～なり and とか～とか present examples, they differ in formality and nuance. ～なり～なり is more formal and presents possible choices without preference. とか～とか is casual and used in everyday speech to mean 'things like (A) and (B),' often implying there are other possible examples.

といった and とか～とか both give examples, but differ in structure and nuance. といった is used in the form AといったB to mean '(B) such as (A)', e.g. サッカーといったスポーツ ('sports such as soccer'). とか～とか follows each noun to list examples, e.g. サッカーとか野球とか ('things like soccer and baseball').

Both や and とか～とか are used to list items non-exhaustively, implying that other, unmentioned items are also included. や is more common in writing or formal speech, while とか is more colloquial. や must follow nouns, while とか can also be used with actions or events involving verbs. Additionally, とか can follow each item in the list, whereas や is not used after the final item.
