"Related" made me think "related how"? "Record some new commits" sounds oddly vague.
Maybe:
Given one or more existing commits, apply the change each one
introduces, recording a new commit for each. This requires
your working tree to be clean (no modifications from the HEAD
commit).

--no-walk can be a bit confusing. I think we should try to avoid relying on the reader understanding it.
<commit>...::
Commits to cherry-pick.
For a more complete list of ways to spell commits, see the
"SPECIFYING REVISIONS" section in linkgit:git-rev-parse[1].
Revision ranges are interpreted as though specified with
the `--no-walk` option; see the "Examples" section below.

This switches between singular and plural.
-n::
--no-commit::
Usually 'git cherry-pick' automatically creates a sequence
of commits. This option can be used to apply the changes
necessary to cherry-pick each named commit to your working
tree and index without making any commits. In addition,
when this option is used, your index does not have to match
the HEAD commit: the cherry-pick is done against the
beginning state of the index.

This is useful for cherry-picking multiple commits
to produce a single new commit.

git cherry-pick master::
Apply the change introduced by the commit at the tip of the
master branch and create a new commit.

git cherry-pick ..master:: git cherry-pick ^HEAD master::
Apply the changes introduced by all commits that are ancestors
of master but not HEAD to produce new commits on the current
branch.

Apply the changes introduced by the fifth- and second-generation
grandparents of master to HEAD as new commits.

git rev-list master -- README | git cherry-pick -n --stdin::
Apply the changes introduced by all commits on the master
branch that touched README to the working tree and index,
so the result can be inspected and made into a single new
commit if suitable.

git cherry-pick --ff ..next::
If history is linear and HEAD is an ancestor of next, update
the working tree and advance the HEAD pointer to match next.
Otherwise, apply the changes introduced by those commits that
are in next but not HEAD to the current branch, creating a new
commit for each new change.
(This is not precisely right, since it doesn’t describe the behavior in some cases of nonlinear history:
. --- . --- . --- . ---. next
/ /
. HEAD .---.
In this case, assuming time flows left-to-right, the HEAD would fast-forward three commits, then cherry-pick the other three. Not sure how to word this nicely.)
