which one is the xprv key ?

You are looking for an extended master private key which is in the first line saying "extended private masterkey".
xprv is the starting 4 characters when you have a master private key for bitcoin mainNet but when you use a different network (TestNet here) the first characters can be different. In this case they are tprv.
Check this out: https://en.bitcoin.it/wiki/List_of_address_prefixes

The next two lines are the addresses that were derived from that master key with the mentioned paths.

P.S. TestNet coins don't have any value but remember that you should never post your keys anywhere like this.
