You will have a lot of work. There are hundreds.
The full list is published by the Israeli ministry of justice and its in Hebrew(also include those which remarked as unlisted).
Please note that not all the organisations titled as terror groups. Some of them titled as "Unlawful Association" and some other titles. Those are not active terror groups but recognized as passive/active supporters(This is my interpretation).
It seems that since 2008 organisations that supported financially terror groups could be titled as 'terror group'. I assume that you won't consider them as 'classic' terror groups(They don't execute terror activity by themselves, but finance this kind of acts).
If you are looking to see all the organisations which are outlaw in Israel according the law of Prevention of Terrorism Ordinance This is the full list.
If you are trying to find which of them is actual terror group in its classic definition, you still have a lot of work to filter them out from this list.
