Any requirement to take a transit visa at Suvarnabhumi airport

I am traveling to Manila Philippines through Bangkok, my flight from Kolkata India to Bangkok (indigo). I arrive in the morning at 7.20. My next flight to Manila is a different airline (Cebu Pacific) with different PNR from 10 a.m. to 25 a.m. Take a transit visa?
And how do I pick up my luggage in Bangkok?
