Close from index strange url?

Question

htaccess

There are many pages on the site with duplicates like this:
site.rf/dir1/ - original
duplicate page:
site.rf/dir1/8%20%28812%29%20941-04-04

site.rf/dir1/8%20% 28921%29%20941-04-04%20%3Cspan%3EViber,%20WhatsApp%3C/8%20%28812%29%20941-04-04

website.rf/dir1/8%20%28921%29%20941- 04-04%20%3Cspan%3EViber,%20WhatsApp%3C/8%20%28921%29%20941-04-04%20%3Cspan%3EViber,%20WhatsApp%3C/8%20%28812%29%20941- 04-04

etc.
I tried to put redirects on them in htaccess, but they do not work.
decided to close them from indexing in robots:
Disallow: */8%20%28812%29%20941-04-04
Disallow: */8%20%28921%29%20941-04-04%20%3Cspan%3EViber,% 20WhatsApp%3C/8%20%28812%29%20941-04-04
Disallow: */8%20%28921%29%20941-04-04%20%3Cspan%3EViber,%20WhatsApp%3C/8%20%28921%29%20941-04-04%20%3Cspan%3EViber,% 20WhatsApp% 3C / 8% 20% 28812% 29% 20941-04-04

Question: did I register the bans correctly?
