Don't seem to be in the dB. From what I can tell, these are part oif the 2011-12 Panini NHL Player of the Day Set (no surprise there). Accoridng to this Ebay listing (https://www.ebay.com/itm/2011-12-Panini-Player-of-the-Day-5-card-Hockey-Set-Ryan-Nugent-Hopkins-/372068662787) it's a 5 card set, although I can't confirm that since I can't find the set on Beckett or Panini.
Based on what you have, we have:
POD1 Alex Ovechkin Washington Capitals
POD2 Tim Thomas Boston Bruins
POD3 Steven Stamkos Tampa Bay Lightning
POD4 Ryan Nugent-Hopkins Edmonton Oilers
POD5 Gabriel Landeskog Colorado Avalanche
*IF* the Ebay listing is correct, we can create the set and add the checklist above. I'm far from a hockey expert, so I'll reserve that for someone who has a little more information...
