In the "filled bands" part of xYplot of the Hmisc package, is there
a way to
have multiple bands with multiple lines? or does it just allow one

No problem as long as you use groups... which means you probably
ought
to be providing a dataframe format with a grouping factor. (At least
that was how I read the help page saying that:

Unlike xyplot, xYplot senses the presence of a groups variable and
automatically invokes panel.superpose instead of panel.xyplot. The
same is true for Dotplot vs. dotplot.

I would give it a dataset that does not have lines coincident if you
want to see them.
(You should also get rid of that space in your color parameter.

So I had an example bit ago had a made up line and CI, now if I
wanted to
make a second line with a CI filled in can I put them on the same
plot?
x<-seq(1,10,1)
y<-seq(1,10,1)
ci<-y*.10
ciupper<-y+ci
cilower<-y-ci
xYplot(Cbind(y,cilower,ciupper)~x, method="filled bands",
col.fill="light
grey", type=c("b"))
x2<-seq(1,5,.5)
y2<-seq(1,5,.5)
ci2<-y2*.10
ciupper2<-y2+ci2
cilower2<-y2-ci2
xYplot(Cbind(y2,cilower2,ciupper2)~x2, method="filled
bands",col.fill="light
grey", type=c("b"))
