true or false kyo have meet kyoko(tohru mother)?

ohhh yes ohhh yes he did

this one day after kyo went to school he went for a little walk(because he dosen't like the feeling of going straight home) and when he was just sitting at a park(i think it was a park) kyoko came up and they had a talk and they stared to like each other

the reason why they don't say that is the anima is ......well..... i don't know really but it dosen't matter if you really want to see it look it the books ( volume 20-21 just to say)

Yes this is true. Kyo met her when he was a child. This is when Kyoko realised she had someone to come home to.

yes it is true its in book 20 and 21

yep!
He also saw Tohru, and thought that she looked lonely...
Kyo thought that it was his fault that Kyoko died...

True (havent read it all, but too many spoilers gave it away)

yes,kyo has met kyoko.when he was little he ran away and kyoko found him. she was looking for tohru at the time. at first kyo did not want to say his name because his name was part of hers. she started a conversation and kyoko opened up to him and kyo could kinda relate to her.
