But I have all session sniffed.(tcpdump)
No only private and public keys.
Can I decrypt the session?

I'm afraid that's not enough.  SSH implements forward secrecy [1],
which means that the server uses temporary (or ephemeral) keys to
encrypt the session traffic.  Having the the private key doesn't give
you the ability to reverse the ephemeral keys and actually decrypt
session data.
