Yes. "Lucy" is but one example of australopithecine. Since the discovery of Lucy there have been several dozen fossils of several dozen individuals discovered. They clearly were early bipedal hominids. The problems you raised have since been addressed and resolved.

Maybe with other specimens, but Lucy is being used till this day; do you agree that Lucy should not be used?

" do you agree that Lucy should not be used? "

Lucy should continue to be used as one example only of early bipedal hominids. It should not be used as the only or conclusive example unless in the context that it "suggests" certain attributes and age.
