You are again fixing only a single thing from all those I mention.
Other than that, my mistake for not looking up what \circle does.
Indeed, this has to be

\floating-markup 15 -60 \markup \circle 1

because 1 is supposed to be a markup, not a number.  Sorry for that.

As for the other problems: I will not keep telling you them one by one.
