Answer 1

Could you please try following, please make sure you clear your browser cache before testing these URLs.
RewriteEngine ON
RewriteCond %{REQUEST_URI} !^/?$
RewriteRule ^ http://%{HTTP_HOST} [R=302,L]
R=302 is temporary redirection, to make it permanent redirection use R=301 in above.

Answer 2

You can just add this rule at top of your .htaccess just below RewriteEngine On line:
RewriteEngine On
RewriteRule ^home/?$ / [R=301,L,NC]
# remaining rules go below this
