You can float it in some warm tap water but it will need to come out of the bag before oxygen levels drop and waste levels rise. Hot water bottles or a light over the tank may also keep temps out of dangerous ranges until you replace the heater. Buy two and keep a spare ready just in case.

Without anything to use for scale, it is hard for me to tell how big your tank is, but in general it seems very small. Also, the water that is in the tank appears very cloudy right now, so that would be the first place to start. Water quality is very important, and will make or break your ability to house and care for fish. I would recommend getting a good filter system (you can visit a local pet store to assist you with brands in your area, as I am not familiar with what you can get in India). Be sure to bring the measurements (height, length, width) of your tank, or the gallons or liters so they can tell you what capacity of filter you will need. Everything else will depend on what types of fish you get - if you plan on getting multiple fish, they will need to be small - a general rule of thumb is one square inch of fish per gallon of water. Depending on the species you get, you may need to also get a bubbler to ensure there is enough oxygen in the water for them, and you will also

Goldfish and Koi are generally considered to be docile fish. I would not expect Porkchop to have any issues moving into his new pond. Make sure to transfer him when the weather is warmer and make sure that his bag used for the transfer sits in the pond for at least 30 minutes to allow him to acclimate to the temperature. Make sure there’s enough air in the bag as well to keep it floating. Lastly, when your room is hot make sure to check the thermometer on his fish tank frequently. Goldfish are considered cold water fish but will live in most temperatures. With a 5 gallon tank, I do not anticipate his water will be very affected by the ambient temperature. If you do happen to notice this, put some dechlorinator in his water and a couple ice cubes but I suspect this will not be necessary. I hope this helps and please feel free to post any additional questions.

It could be a minor bacterial bloom due to the filter not running. You can perform a partial water change, no more than 30%, and run the filter. Use only aged or conditioned water that is temperature matched to prevent stress or shock. It should clear up after a few days.
