Hello Dtonyantony,
What has happened to your earlier good punctuation?
You should not place full stops/dots before a question mark.
All sentences need to begin with a capital letter.
Why don’t you play with me?
When will you come back?
Why did she do that?
Perhaps you would like to correct the rest of your sentences?
Thank you for the corrections.

Is there a reason why you haven’t used capital letters, Filbert?
Note the spelling: ‘happiness’.
Hi B.vidyullata,
which color do you like? Pink or Red? ← Which colour do you like? (capital letter). Better punctuation would be:
Which colour do you like: pink or red?
Otherwise ‘pink or red’ is not part of a complete sentence.
When do you go to school? <–correct
Who accepts this letter? <–correct
Whom should I contact on the issue? <–correct
How long it may take to receive that letter? ← How long will it take to receive that letter?
Where is the Golconda fort situated at Delhi? Where in Delhi is the Golconda Fort situated? (Otherwise it sounds as if you are answering your own question with the last 2 words.)
Whose pet is this? <–correct
What course you are taking? What course are you taking?
Which book is religious? <–correct
What are you doing now? How about today? When can you came back to me? Where are you? Which job do you like?
