Hindering and beneficial natures means which stat it gets a boost in and which one falls depending on your pokemon's nature. For example Azumarill has Jolly, which is +Spd, -Sp Atk. It means that it's Sp Atk stat will only have a maximum of the hindering nature while it's speed will have a maximum of beneficial nature.

First of all, you only want ONE TYPE of attack on EACH POKEMON. Your Azumarill has THREE water attacks. Big waste. Just use surf. Same with a lot of your other pokemon.

Second, get better items. Sharp Beak and the like suck.

Third, get proper natures. Natures influence how well your poke performs a LOT. You don't want Jolly on Azumarill if you're using it for Special Attacks.

Fourth, Hyper Beam sucks. It's only good on say, Porygon Z which can OHKO Blissey after 1 Nasty Plot.

Sorry to tell you but none of those pokes would be even SLIGHTLY good in a competitive battle. You should look at some of the other RMTs and their criticisms before you make your own team and post it.
