Oui, je suic'est le cas.

Tag questions/answers ("are you having fun - yes, I AM) don't work in French, they're specific to English syntax (and also to some Celtic languages, AFAIK, but it's not the subject here)
In this case, the most natural answer would be "oui" or "oui, c'est le cas" if you really want to emphasize

J'aime bien apprendre de nouveauxlles choses à propos de la France et de la culture de française.

"français" is already an adjective, so you don't need "de"
nouveau, nouveaux (masculine) ; nouvelle, nouvelles (feminine) ("chose" is a feminine word)

J'aime bien apprendre à proposconnaître de nouveaux lieux que je veux/voudrais visiter une jour et des choses je peuxourrai faire quand j'arriverai làe serai en France.

"apprendre à propos de" is a literal translation of "learning about smthg" which doesn't really work with French syntax
If you've just learned about a place and aren't sure whether you'd like to go there or not, "voudrais" or "pourrais" would be better
Future tense => pourrai
