Hi,
Yep, this is possible. Using one of your urls, set the first box on the redirect manager page to en/component/content/article/1-blog/132-are-horses-studious.html and the second box to the url you want to redirect to.
For urls, with query strings (?option=com_jnews), your not going to be able to use the 301 redirect tool in mojo. For those, you could simply redirect the actual page (index.php) in your example to the homepage of your mojo site.
HTH,
Joe D.
