  Is it the case that only the first add to the branch node will be added,

It might help to clarify the terminology here.  Subversion's own
documentation does not use the term "queueing" at all, and does not use
the term "add" except in the narrow sense of an operation that results
in a new versioned directory entry.  «add» is a local operation (doesn't
contact the server).

It's not clear to me what sense you use those two terms in.  In
particular, when you write "until that first node is committed", you
seem to be assuming some sort of interim state, a "node" that has been
"added" but not been "committed", and that affects other users.  There's
no such thing.

The repository is a versioned filesystem tree.  Changes to that tree
(commits) are made transactionally.  A commit that has not completed
does not affect other commits in any way (cf. ACID).

Yes. Branches are nothing special in Subversion, just another folder
(copied from somewhere). Then you may, by convention and project
guidelines, have restrictions on what you can do and should do in a branch.

You can commit as you would normally do in /trunk. Any conflicts will be
managed when updating the working copy (before commit, if needed).

(You can configure a file to require locking, but that is a separate
question from branching. To edit a locked file you must aquire the lock
from the server and only one person at a time can hold the lock to a
certain file. There is no locking on folder level).

Kind regards,
