I'm newbie and i'm still confused about this :

1) Newer use R-Gacha tickets donate them all 1 at a time. Players get one R-Gacha from daily quest.

Do you mean i must gift it to Kurito ? and what i get from it ? i should give it 10x R-Gacha Ticket ?

Yup, to Kurito. And no not all 10 at a time, either 1 by 1 or 3 of them. Check the thread with kurito value of items and what can u get in that range.
Kurito has a N, R and a SR card that u can get, beside other goodies like Wild Card 1/3/5.

yup give to Kurito, and no give 1 R-Gacha to Kurito
