I made transaction 3 first, then 1 and 2 (not remember the order between 1 and 2)
As mentioned by ranochigo, you have made the transaction 1 before transaction 2.
If you want these transaction to be confirmed fast, you should bump the fee of transaction 2
Note that with bumping the fee of transaction 3, you invalidate transactions 1 and 2 and with bumping the fee of transaction 1, you invalidate transaction 2.
