As far as I know, any that can be tied on a bight can also be tied by using a free end, but not necessarily the other way around. The following are only some knots that can be tied on a bight:
Clove Hitch
Constrictor (ABOK #1249)
Double Constrictor (ABOK #1252)
Butterfly (ABOK #1053)
Handcuff (ABOK #1140)
Tom Fool (ABOK #1141)
Jug Sling (ABOK #1142)
Double Splayed Loop (ABOK#1100)

Slipped Overhand Loop, Slipped Figure 8 Loop, Slipped Figure 9 Loop, etc.
Pile Hitch, Double Pile Hitch, etc.

Here's a quick test to determine if you can tie a knot on a bight: After slipping the knot off the object, can you untie the knot completely without having access to the working end? If yes, then you can tie that knot on the bight somehow. For example, a normal Timber Hitch (ABOK #1665) slipped off the object cannot be untied completely without having access to an end. So, a Timber Hitch cannot be tied on a bight. Some of the knots mentioned by Hrungnir don't pass this test.
Some hitches:
Timber hitch, round turn and two half hitches and buntline can all be tied using the bight as a working end.

If we're allowed to use a bight as a working end, then every knot can be tied on a bight.
