I generally agree with Loki-L's comments, except:

Quoting Loki-L <loki.laufeyjarson.ffml@gmail.com>:

"Yes, thank you."  Then the boy sat up and started looking around for the
one who ran him down.  He saw him instantly; a slightly muscular boy with
black pants, a red Chinese shirt and a long pigtail.  Ranma, the girl had
called him, was being confronted by the wooden sword boy.

I think you are supposed to keep speech and action always separated. This
should be two paragraphs. You are doing this a lot, but since I am not
entirely sure that it is a mistake I will not point it out every time.

Opinions differ on this, but I think having speech and action in the same
paragraph is a perfectly fine thing to do. Most if not all professional authors
mix them all the time, and it's good to have some variety in the way dialog is
narrated. Having a whole series of '"Blah blah blah," he said, "and blah and
blah."' paragraphs can get monotonous.

"Turn and face your executioner, coward!"

Here you not accompanying the speech with anything, which might be
wrong, too. I think that if this is a mistake, than it is a far less
severe one than the other way.

This is also not a problem. As long as it can be inferred who the speaker is,
you don't need an explicit tag. In fact, a standard way to clue the readers
into who is speaking is to have the same character be the subject of an
adjacent action. For example:

Whatsisname the Dragon Boy shook his fist. "Turn and face your executioner,
coward!"

In this case, I don't think this would be necessary either, as it's clear who
the speaker is from context.
