Definitely!
You can also do
from("foo").to("bar", "baz", "sec")
to save a bit of typing.
By default things are chained piplines; so the output of "bar" goes to
"baz" etc.
If you don't want that and want to clone the message exchange to each
destination you can use multicast...
from("foo").multicast().to("bar", "baz", "sec")
By default things are synchronous; so the same caller thread invokes
bar/baz/sec - which is useful for declarative transaction handling
etc.
If you want to make things async, just add a seda step...
from("foo").to("bar", "seda:baz-n-sec");
from("seda:baz-n-sec").to("baz", "sec")
