Thank you very mach I hope this is addresses not from your wallet 
The private keys that shorena posted are for testnet, so they don't matter. So only used addresses have "label" and "change" & "reserve"addresses is not important - right?
Those addresses are still important. After you send from you wallet, the change addresses are for your change and the reserve addresses are where you get new addresses from. When you click on "New" in the receiving addresses window, you are getting an address from the list of reserve addresses. Change addresses will also be able to spend Bitcoin as Bitcoin Core uses a new change address for the change of every transaction.Thank you @knightdk to clear for me - I like to migrate to another wallet like Electrum so for me was important to know
So I can filter only "label"&"change"
