I have a 2.5 gallon water tank and one betta fish would I be able to have a 5w heater ?

Bettas are pointless fish. They are for 6 year olds to look at and say 'Mommy, pretty fissy'. Little more.

You need to get a bigger tank. Bettas need 5 gallons minimum.
What wattage heater you need depends on the ambient temperature. A 25 or 50 watt heater should work for a 5 gallon.

The heater should be at least 15 watts.
