Hello @frankie97
I love how you outlined the different keys offered to you on creation of your account. Happy you understood the functions of the different keys. I will love to point out that you can login to your wallet with your posting key. I advise you always used your post ting key rather than the active key. Your active key should be used only when u want to confirm transactions in your wallet.
Lastly, the question 4 and 5 is about transferring of token which you have explained meaning you have and understanding of it. Update with screenshot, same too with powering up your account.
