Hello,
sorry for delay.
To don't show capacity, you can uncheck checkbox "Display capacity" near "Total capacity" in object details.
You can set how many hours/days user can book during one reservation "Reservation types ">"Limit restrictions", but you can't set how many objects user can book. Choose to show "when must be deposit paid" , will be probably added in to the one of the future release.
We can add these features immediately during custom paid support (
