nope, what you posted in the screenshot wont help you.
some are private keys but for addresses that are generated by this extended public key.
how many lines you have inside labels object? 159?
you need to find keystore string or other private keys like the ones you posted
how to count them? What I have in labels is, as you can see, private keys that have 0 balance, or old transactions, some addresses, and a hash of transactions. Can I send this to you so you can help me?
