It's hard to know how to parse this in a general sense if you won't tell us the "rules" that are used to produce the data. As it is, your dataset is very inconsistent.

Some lines have a field name and a value: 

Number: 634321

Some lines have two field/value pairs, with no separator! 
age: 27 hair colour: black

Some lines have a value, with no field name: 
Graq
Agnostic

And toward the end you have a series of values, followed by a series of field names: 
jameson
bells
guinness
favourite
detests
likes

If there are in fact any real rules governing the data, you should tell us. Better yet, you should if possible change your data structure to something easier. I'll bet that you could parse this easily: 

# DATA: Start
name: Graq
religion: Agnostic
Number: 634321
age: 27
hair colour: black
height: 73
weight: 123
legs: 2
arms: 2
favorite: jameson
detests: bells
likes: guinness
# DATA: End
