Accidentally the number of function definitions does not help the clarity of
the program, even though it's completely unclear to me what exactly you are
trying to do. :-)
I rewrote your program a bit combining the definition of the functions, the
comparision of the functions and removed the chance that your program goes
on the define/compare values that have not been defined.

largura_aeronave = 0

global altura, altura_aeronave, comprimento, comprimento_aeronave, \

print 'Volume largo demais!'
elif not altura <= altura_aeronave:
print 'Volume alto demais!'

Alright this code is actually littered with bugs, but don't feel bad,
because as you state you are new to the whole programming thing. I'll try to
explain the things i see going wrong (please take into account that i'm also
a new pythonist ;-))

You get the error 'variable undefined' because you are declaring a global
in an incorrect manner. The correct manner is to define the variable in the
global scope then start a definition, declare that you are using a global
variable and then assign it. Like this :
bla = 'Hello world'
def func():
global bla
print bla
***
If you do :
porao = raw_input()
You'll define the integer value as a string, not an integer. If you are
sure that only an integer will be entered use input() (slower) or
int(raw_input()). In either case you should use try and except clauses more
in your code because if not a 1 or 4 is entered your code will continue
without having the variables declared! Leading to other errors.
***
Now suppose you get the definitions using globals correct then you'll get
new errors stating that an 'int' is not callable.
This happens because you define for example altura as an integer and then
also define a function called altura. If you now use :
altura()
It'll try to call the integer object and will fail.
Easy solution would be to make the function something like alturadef()
***
As for your identation you should use consistent identation... I suggest
using python -t or python -tt to compile your script and it will give
warnings/errors where the identation goes wrong.

Here's how i altered your code (quick and dirty probably, it should be
more clean using try and except clauses and what not) to get it to work but
you can probably better look that up in a python book and then return to the
list if you don't understand it :
#Ok,this is supposed to be a 2 option choice between values 1 and 4,
#i want the value to determine the variable values inside the function
altura_aeronave = 0
largura_aeronave = 0
comprimento_aeronave = 0
comprimento = 0
largura = 0
altura = 0
def porao():
global altura_aeronave, largura_aeronave, comprimento
porao = input()
if porao == 1 :
altura_aeronave = 111
largura_aeronave = 112
comprimento = 211
elif porao == 4:
altura_aeronave = 112
largura_aeronave = 113
comprimento = 212
else:
print "Porão inexistente"
#These three functions were supposed to get input from user so it can be
compared
#with the values determinated(determined?)above
def larguradef():
global largura
largura=input()
def alturadef():
global altura
altura=input()
def comprimentodef():
global comprimento
comprimento = input()
#These are the comparison functions
def largura_compativel ():
global largura, largura_aeronave
if not largura <= largura_aeronave:
print 'Volume largo demais!'
def altura_compativel ():
global altura, altura_aeronave
if not altura <= altura_aeronave:
print 'Volume alto demais!'

global comprimento, comprimento_aeronave
