If I understand correctly, you want to pull out these individual pieces of information from a single field and display them as their own fields on the Discover tab? It would be best to do this at ingestion time with Logstash or Ingest node, but you could also create a scripted field for each new piece of data you want to pull out. The docs are a little out of date right now, but in 5.0 you'll be able to create scripted fields using the new Painless scripting language which will allow you to create string type fields with a regex.
