iPhone backup failure

Hi I recently got this new I phone in the past year but all my old stuff from my previous apple phone never backed up on this phone when I done it on I cloud..

is there anyway you could help me do this now as there is really important stuff from my previous apple phones (phones) that I would love to have on my current one.. please see pics attached below of old phone (phones) that I think never backed up to this one..
