Does anybody know what items i need to enter the different towers?

You need nothing for the Snorlax Tower, coins for the Blissey Tower, battle points for the Forest Tower, battle points for the Marine Tower, battle points for the Lava Tower, a shadow key for the Shadow Tower, a cursed key for the Cursed Tower, a golden key for the Golden Tower, and a rainbow key for the Rainbow Tower. I am not unsure about the Unown Tower and I'm fairly certain you need a luminous key for the Luminous Tower.

You don't need points for forest-fire

Oh, it gives you points, I thought that was the price to challenge it.

Nopperz

The towers are so challenging that it is very hard to beat even the second poke!!

unown tower is odd key, you can use as many times as wanted

To enter the unown you need a normal key

where do you get those keys?

It is not a Normal Key it is as Magick stated above an Odd Key needed to enter the Unown Tower. You recieve an Odd Key by defeating MissingNo. Travel to Fuchsia City and go to the Safari Zone map. Enter the building and exit through the door which normally says something along the lines of "I wonder how to unlock it". The map will have the old generation I graphics but they will be all distorted. Walk around and it should only take about a minute to find a MissingNo.

its simple...
