My first few times in a sauna, I stayed in for around 15 minutes. Now I stay in between 25 and 30 minutes, however...
You should always listen to your body. It will let you know when you've had enough. Most sauna bathers stay in for 30 minutes max, but some go longer - as much as 45 minutes to an hour.
If you're a beginner, you can do 10 or 15 minutes sessions at first. You can gradually work your way up from there.

It requires you to be very obese to be even be able to lose 1.5 kg with sauna.The thing with sauna is that it causes you only to sweat, it is a way to cleanse yourself.

It is safe to use sauna every day, as long as you don't do it for long periods at a time.
Depends how hot the sauna is. If it's really hot, you can't usually stay longer than a few minutes, but if it's around 60-75°C, you can stay a lot longer, even up to an hour or so if you have water with you for drinking.
Id say about an hour or so, however, the weight you lose with only be water weight.

A jacuzzi is similar to a bath with a temperature of around 100 degrees of water. A sauna in comparison is a room that is filled with steam which is a gas. They are both harmless and can help you to cleanse or detoxify yourself but if you stay in for too long your skin can become prune like. Neither have any negative long term health effects. It is suggested that you not heat up a jacuzzi or sauna too high or you may suffer burns.
