what would be the cheapest way fly to Amsterdam from Kathmandu Airport
Hard to say without knowing your exact travel dates - have a look at Expedia or Kayak instead.

what's the cheapest way to Travel around Netherlands By Bus or Train??
Train. Generally speaking, intercity transportation by bus is not a feasible option, public transport is basically centered on the rail network (see [www.ns.nl], the Dutch Railways website), with bus connections to nearby towns and villages (see [www.9292ov.nl] for door-to-door travel advice including train, bus and other modes of transport).

How can i go From Amsterdam to Barcilona/Spain?
Train is a nice option if you have time, but plane is cheaper and faster. Have a look at [www.skyscanner.net] for flights, or [www.ryanair.com] for flights out of Eindhoven.

It's difficult to say what would be the cheaper flight from Kathmandu to Amsterdam because you have several options and it'll depend on your travel dates.
However, for flights between Amsterdam and Barcelona you can try Easyjet, Vueling or Transavia. All of them are low cost airlines but, as always, you should read carefully their terms and conditions to avoid surprises.
