First let me say my Japanese is not really that great. If you want more help you should probably go here:

how to call bf/gf in japanese. i mean how do they call each other?
and "what are you doing now" wa nihon-go de nan desu ka?
nani o shimasu ka? this?
Nani o shimasu ka sounds alright to me, although if you want to emphasize "now" you should probably add "ima" e.g. ima wa nani o shimasu ka.
Again, you should probably ask the experts in that thread I posted above.

Sifu can explain abit or not?
From your guide, if I'm not wrong you used:
eg. Haha to chichi to ani to watashi desu.
Can I change the 'to' with 'mo'?
If cannot when I am suppose to use 'mo'?
p/s: I accidently bump into this thread and started to read yesterday. Thanks for such a great guide. Really helpful for people like me who wants to learn basic Japanese
@shinz: From the post if I'm not wrong it is boifurendu for bf. For gf maybe girufurendu?

Well, the way I understand it, "to" is a connector and works like the English word "and". On the other hand, "mo" is more like "also" or "too", so there's a slight difference there.
Example:
Watashi mo ikitai = I also want to go

yeah i know that but how do they call each others?
just name? let say i use "dear" in english, what is it in japanese then.
Boifurendo is a romanised or westernised way of saying boyfriend.
I'm not too sure what the Japanese word is for "dear", I'm guessing maybe koishii? Again, you should probably ask in that Japanese speaking thread.
