 Do i need to pay every month or every three months to LSP's? Or is it just a one time payment?  
 You only pay that fee once to open the channel to the LSP and then can use the channel until it is closed. I have been using Alby Hub for a few months and not had any channels closed on me.
There are a variety of reasons a channel could be closed and you can get some info here:

 Which LSP you're using?  
 I have a channel with Megalith and LNServer.
