I would think it likely there is a limit to how much you can attend to. You might be able to have three or four arms and sense them and control them but there would come a point when you cannot attend to all your arms. It’s a LD goal of mine to have say, a hundred arms but I have not achieved this yet so cannot comment from personal experience.
