Answer

Ah...but I am invading the Hindi section!  Sorry.  ha ha

Answer

"She likes to gossip just like the rest of her family."

This is an adequate sentence also.  Perhaps a comma can be added to indicated a pause as follows:

"She likes to gossip,   just like the rest of her family."

Answer

"Although we protested against many acts of violence in our cities, there's still a lot of intolerance present in our villages."  [Again,  eliminate the contraction  unless you are quoting speech.  Use   THERE IS.]

This is generally a good construction.  Nice writing.

Answer

Without parents' guidance at the initial start of our lives, life would've been difficult for us.
[Do not use  written contractions  unless you are quoting dialogue.
  Here,  use  WOULD HAVE.]

You can remove INITIAL because  the start is "initial".
 
   "Without  parent's   guidance  at the start of our lives, life would have been difficult for us."

You could also express the idea this way, which is how I would word it.

"Parental  guidance at the start of our lives,   prevents   many difficulties  later in life."
