You should start looking what you're doing (i.e. attempt to learn) instead of making transactions after transactions with no idea at all what you're doing.

This time you were lucky, the mempool got cleared and all the transactions were processed, no matter how small were the fees. But in a worse situation you may have paid even more since you've made the actual situation worse, instead of improving it (the only funds you should have spend with higher fee you've spent with even lower fee).
