will it work?
7-speed chain might run cleanly through 8- or 9-speed jockey cages. In many cases, 9/10/11-speed chain will actually run fine on "7-speed" chainrings and sprockets, as they are often well under 3/32" true width. If in doubt, measure. There's a reason why a modestly priced digital caliper is near the top of any list of tools to buy.

9 speed newish derailleur (tiagra), 7 speed cassette (HG50) and a 3/32 7spd chain.
Will that chain work on the rear?

No tiagra, but maybe a 600 tricolor. Still - will it work?
