Yes. Lorenzo is right. All those patterns are coming from the book
GoF95 and all of them are real design patterns.

Anti-patterns are things that can happen in software done by beginner
and that are really easy to see. For instance, the God class (also
known as code bloat), or the spaghetti code. Anti-pattern puts name of
bad pratices and show you how to fix those things in your code. The fix
is done by refactoring the bad pieces, but they explain which pattern
can be used in order to not get into another anti-pattern.

There is tons of list of anti-pattern on the Internet. Just take a
look... it won't be hard to find a few.

Looks like a term paper question.

Some folks have made the case that 'singleton' is a pattern when used well,
and an anti-pattern as commonly used. That's the only one of the GOF
patterns that I know of that can be seen as both, but I suppose any pattern
used poorly can be considered 'bad'.
