Some novels no longer shown in trial read ,when it supposed to be out earlier
will they be added in future or some copyright issues 
Where is novels
Hmmmmnmm
EternalAngel They might return to the Trial Read in the future, but the chances are pretty low, so don't have any high expectations.
RABBITICOL ok , but again new novel replacing the old one today.
does more readers mean better chances in picking it ?
EternalAngel it depends on chapter unlocks with Coins. The more readers spend paid Coins to unlock the book, the higher its chances of getting picked.
Fast Passes and Free Coins don't contribute anything.
