The (P) means it's personal te/pots and cannot be traded. with your current number of pots/te, I'd say getting any 5* is unlikely, and at best you can get one of the worst common 5* (like Emma or Lucrezia) if someone decides to be nice to you. My recommendation, collect more nonpersonal te/pots and/or max a bunch of 4*, and you should be able to get a 5*. Decent common 5*s are generally 10 to 20 te (max 4*s are worth about 3 or 4 te) depending on rarity and stats, however you can get one of the really bad 5* for less than 10 te depending on the seller. However I would recommend saving up for a decent 5*, as the super cheap 5*s are pretty bad. Also potions are worth either 1 te or .5 te, as the worth varies from seller to seller.
