According to my understanding, I will give you some suggestion.
1.(1) What is the difference between VMFS VMware storage - Datastrore and VMFS VMware storage - Database
I think there is no large difference between VMFS VMware storage - Datastrore and VMFS VMware storage - Database. It may let you to select an appropriate storage pool type to match your specific application. Also may there have better compatibility.
(2) What is the difference between VMware SAS storage pool using RAID 5(4+1) and VMware SAS storage pool using RAID 5(6+1)
RAID5(4+1) and RAID5(6+1) all belong to RAID5 type. They will consider the balance of performance and capacity. RAID5 allowe one disk failure. When occurred one disk failure, can rebuilt disk through parity. Due to RAID5(6+1) use 7 disk drives to make a storage pool, RAID5(6+1) provides the capacity will be greater than RAID5(4+1). But when rebuilt disk, the risk(May occur second disk failure on rebuilt time, then bring about data loss) of RAID5(6+1) will be greater than RAID5(4+1). For more info you can google RAID5.
3. How many % of the total storage will be assigned for protection storage in idle scenario.?
In general, you just follow "Recommended Protection Size". But the Protection Size doesn't small than "Minimum Protection Size".
4. In our case, total storage size is 6x900GB=5.4TB and we are planning to go with RAID5. Hence total usable space would be 3.6TB.
We can have one storage pool with 3.6 TB and create two LUNs on it. Or create two storage pool with 1.8TB and assign each LUN. What is the best practice?
You only have six 900GB disk drives. So, you only can make RAID5(4+1) storage pool. Left one disk drive you can make to hot spare disk. Then on the RAID5(4+1) storage pool with 3.6TB, you can create few VMFS LUNs.

Hi Bineesh,
Please find below documents for VMWare configuration with VNXe and storage pool information.
EMC Storage System for storage pool information
VNXe with VMWare for VMWare configuration
Also, Minimum RAID 5 configuration is RAID5 (4+1).
