أحسن الله إليكم، شيخنا If one lives with his parents and is young, should he try to give out money if he sees beggers? Some beggers could be fake.

Giving is a sunnah and not an obligation, so if you do not know his state give him what is easy even if it is little. If the money is your parents' then do not give from it beyond the small amount you know they are content with, without asking them.
