Yes. You can criss cross the country o as many trains in one day if you like...
I don't know about 2nd class, but on 1st class, I had to pay a 30 euro surcharge per journey (mainly because in 1st class, I got a meal and free drinks). For the high speed trains you need to book the seat reservation and pay the surcharge in advance.
