He requested his father to increase his pocket-money.

The correct indirect form of the given sentence is:

He requested his father to increase his pocket-money.

The other options are incorrect for the following reasons:

• He requests his father to increase his pocket-money. - The present tense verb "requests" is not appropriate in indirect speech, as the speaker is reporting what was said in the past.
• He requested his father to increase them pocket-money. - The pronoun "them" is incorrect, as it refers to multiple people, but the speaker is only requesting an increase in their own pocket-money.
• He requested with his father to increase his pocket-money. - The word "with" is unnecessary in indirect speech.
