All of them.  The chosen ones are marked "installed".

(Babeld will actually discard some routes, you can disable this
optimisation by setting the "keep-unfeasible" option.  It's a good idea to
set this option on nodes you use for monitoring.)

No single node has global information in a Babel network -- nodes only
know in which direction to push packets, that's all they need.

There's babelweb, that displays the two-hop topology and can monitor
multiple nodes simultaneously:

There's a live demo online, but it's broken right now:
