など, which means 'et cetera', 'and so on', is similar to and can be used in conjunction with や, but is generally used to conclude a list of examples, or samples of a potentially larger list.

In the first example 'and such like' may be implied, but nado is often used in this way without necessarily literally meaning 'and so on', I think maybe it makes the sentence less rigidly precise.
Amatuka
The second example is the standard 'list' usage. The particle 'ya' can be used in place of the commas.

等、、、 is also used as english "etc..."

なんか and なんて have the same meaning but are colloquial terms. Another usage of those three is when you don't think much of something or contem something.

Ex.3218: Isnツエt apple :ringo?
Futaro
Apple juice is りんごジュース or アップルジュース.

I think など, like なんて, can also indicates that the speaker is shocked or outraged. I think it's the case in this sentence: かよわいものから りゃくだつなど!

Could など be used after a series of も instead of や?. For example "He stole money, the credit cards, a watch, and other things". お金もクレジットカ−ドも時計も服など盗んだ
