what is the mean of fund pending clearance ?
It means that those funds are not yet available for you to withdraw from your account.
After an order is marked completed either by the buyer or system, it takes on average about 14 to 17 days for the funds to clear and for you to be able to withdraw them to the funding source you chose when you signed up here.
Suggest you read the Terms of Service at the bottom of the Fiverr main page for the rules as to how Fiverr works.
Everything is explained there in great detail.
can we use our money without clearance?
No. Again, read the ToS and a dictionary.
Pending means not yet.
