If the propagation is 0%, can it go back up or should I not keep my hopes up. What do you suggest I do at this point?
Unless you are in a hurry, I suggest you wait a few days.
The transactions will probably not confirm, and 4 or 5 days from now you will probably see them disappear from your wallet. When that happens, all the bitcoins that you sent with those 5 transactions will reappear in your balance.
If you are in a hurry for some reason, then your best option is probably to find a technically knowledgeable person that you trust to help you create, sign, and broadcast replacement raw transactions that spend the exact same inputs, but which send the entire balance to an address that you control.
It should just require a single replacement transaction with a 0.0001 BTC or 0.0002 BTC transaction fee and would then likely confirm within an hour. Once that replacement transaction is confirmed, you would see the 5 pending transactions vanish and your entire balance (minus the 0.0001 BTC or 0.0002 BTC transaction fee) would be once again available for spending.
