:All my spare chains are 9-speed ones. My friend needs a new chain but his bike is either 6 or 7 speed rear cluster. Will a 9 speed chain work on a 6 or 7 speed cluster?

Yes, but shifting may be a little iffy if it's indexed. Friction, no
problem. But a new 8 speed chain is only about 10 bucks, and is
likely to last longer, and available at any decent bike shop.
