These are not perfect definitions, but can serve ur purpose

Open Ports means ports thru which another machine can talk with ur machine or vice-versa.

Closed ports means those ports which can't accept/transmit data.

Listening ports means ports which are ready to accept data.

Established ports means communication is going on thru those ports.

TCP/IP, UDP & others are Protocols.

Basically, protocols are the rules which DATA follows while transmitting.

I told u as simple as I can. Remember, all this is technically slight different.

if i want to use a port for a bittorent client, i need to use listening port?

Yes.
But you can manually open ports if you want.

i did netstat in cmd, saw a number of a port near Listening Port and i used it in Azureus but nothing happens and the test still says it is closed.
what does it mean ?
what to do ?

most probably they are used by another program.

Try to open some ports manually & then try to connect thru them
