The second one I can almost read it... Seems to be a greeting card from a neighbour: Good neighbour (or wishes), family(?), friends/friendships, from Mr and Ms. H. de Cannecy? Caveny? Who is wishing you, as well as your dear parents, a good and happy new year 1904.
The third one is from a lover: "Loving kisses from your Antony", fourth seems to be in Spanish, so I won't attempt a translation, Fifth is German, I only can read the last word, which means "colleague", probably "to my colleague(s)". No idea about the last.
