Single challan for all sections of tds payments for one month

Yes you can do that, Section mentioned in Challan is no more relevant. If one have paid challan under section 194C, the same can be utilized for the payment of TDS deducted u/s 194J or combination of sections at the time of filling TDS return. 

You may refer Circular No ‐ E/257, 12th September, 2014

YES 

YOU CAN DO THIS 

BUT I THINK THAT TDS DEPOSIT SPERATE CHALLAN  AS PER SECTION IN WHICH TDS DEDUCT IS MORE BENEFIT 

BECAUSE THERE IS DIFFERENCE % RATE OF TDS DEDUCTION  AND HELPFUL  YOUR ACCOUNT BOOK MAINTAIN AND VERY USESFULL WHEN YOUR AUDITOR ASK YOU ABOUT THIS 

GOOD LUCK
