Genki desu. Anata WA genki desu ka? I am well. How are you?
This is usually translated into English as 'How are you?' It is used frequently in Japan as a general greeting. It is used in its polite form with the honorific O in front, "O genki desu ka?" or informally "genki?" or "genki no?" Genki means in good health and feeling well. You are literally asking if the person is healthy and doing well. A reply to this could be "genki desu" or "hai, genki desu".
Watashi does mean "I" but it doesn't mean "I am" unless you put "wa" after it. If the word "Watashi" has "no" after it, it is actually "my". "eien" is the word for "Eternal, or permanent" ect. and "Tomodachi" is "Friend". plus the fact that "anata ha" in this sentence could mean along the lines of "you". So i think that this sentence says : "You are my eternal(best) friend."
This can generally be translated as: (by line) O genki desu ka? How are you? Watashi ha genki desu. I am well. Anata ha daijoubu desu ka? Are you all right?
I think you mean "genki desu ka". The correct way of spelling it in English would be "ogenki desu ka". It is Japanese for "How are you?" One would usually answer by saying "Genki desu. Anata wa?' which means "I'm fine, and you?"
if someone asked you "ogenki desu ka" (how are you) you can answer him by saying "genki desu" (i'm fine)
genki desu ka or ikaga desu ka
It's a greeting, "Hello, how are you?" (Konnichi wa - Hello/Good Afternoon, O-genki - Health, desu - an equal sign, general means something 'is' something, ka - basically a question mark). A response could be "Hai, genki desu. Anata wa?" (Good, thank you, and you?)
'(Watashi no) ryoushin ga daisuki desu.'
simply, Desu. eg. who are you? - anata wa dare desu ka? where are you? - anata wa doko desu ka? are you ill? - anata wa byouki desu ka? are they new? - arera wa atarashii desu ka? ect. Desu means: Are, Is, and am.
Fine as in "I'm doing fine?" I don't know enough from the context of your question, but I'll give you a sample dialogue guessing what you mean: person A: O-genki desu ka? (How are you?) person B: Ee, genki desu. Anata wa? (I'm fine, you?) Pronunciation: O = oh genki = ganky desu = dess ka = kah ee = eh (but with a longer ay sound... extend the vowel somewhat) anata = A's pronounced like "ah" as in "father" wa = wah.
