I hope that I can share happiness and harmony with my couple. ???
Is he or she into some odd relationship?
I think you mean companion instead of "couple."
This one below makes more sense to me.
I hope that I can share happiness and harmony with my companion.
I hope my companion and I will give warmth and happiness each other. ??
I think you mean "I hope my companion and I will give warmth and happiness to each other."
This is okay grammatically, but no one would say "I hope my companion and I will give warmth and happiness to each other." in the US.
