'Das Zeug' (stuff) is a collective term and is almost always used in the singular, even when many different things are meant. A plural form is not common in standard German.

In the meaning of 'Kram' (junk/odds and ends) or 'Sachen' (things), 'das Zeug' (stuff) is very colloquial. Depending on the context, it can sound neutral, but often also slightly disparaging or dismissive.

I don't understand why you spend so much money on this useless stuff.
The idiom 'das Zeug zu etwas haben' (to have what it takes for something) is a fixed expression. It is used with 'zu' + dative or with 'dazu' to say that someone has the necessary talent or potential for something.
Diese junge Sportlerin hat das Zeug zur Weltmeisterin.
This young athlete has what it takes to become a world champion.
thing / matter
Sachen refers neutrally to personal belongings and can mean individual items. Zeug groups such things together colloquially as an unorganized amount and often sounds disparaging. Use Sachen as a neutral term; when expressing annoyance or contempt, Zeug is more suitable.
