OBD2 P0171, P0133 & P2195 on 2004 Toyota Corolla?

This morning I got a check engine light on on the panel of my 2004 Corolla. I used my OBD-2 tester and obtained the codes of P0171, 0133 & 2195. I would appreciate any expert opinion from this forum on how I can deal with it myself, if possible. Thanks a lot.
