i need 5 of them. can someone tell me how to make them and if i need to do any quests to make them.

You need pots, buckets and bones and visit the shrine or temple north of Port Phasmatys. No quests are required to make them, but entering Port Phasmatys costs 2 tokens unless you have done Ghosts Ahoy.

You'll still need to do Priest in Peril to get to Morytania, but I doubt you haven't done that one. Check Tip.it's Prayer Guide to get a detailed walk-through on how to get ecto-tokens.
