it acts as acid base indicator
Yes you can use methyl red, methyl orange, bromophenol blue and other indicators instead of phenolphthalein in the acid-base titration of NaOH.
to determine the end point of titration
Phenolphthalein indicates red for acids and blue for bases.
it acts as acid base indicator
it's not in all cases. Only for titration of weak acids.

It's the colour indicator you watch for during the titration.
phenolphthalein
phenolphthalein is one i know.

it is used as an acid-base indicator
To indicate when the substance has been neutralized
This is so since the pH at the end point of Phenolphthalein is 9.1 and methyl orange is 3.7. For a strong acid strong base titration which the end point is between 3-11 phenolphthalein is used
