Which cameras use the BLS-50 battery?

OM System OM-5 Mark II, OM System OM-5, Olympus OM-D E-M10 IV, Olympus OM-D E-M5 III.

Can I use a BLS-5 battery instead of a BLS-50?

The BLS-50 / BLS-5 batteries share the same shape and contacts, so they fit the same cameras. Older versions hold less charge, and some newer bodies limit features such as in-camera USB charging or the fastest burst with an older cell, so check the camera maker's compatibility note.
