Making soda with yeast
It is easy to make soda by adding sugar and yeast to a bottle of water and closing it tightly. However, checking different recipes, I did not get what is the best condition for this. I have a couple of tiny questions to find the optimum treatment.
I added 1/2 tsp instant yeast (baking yeast) and 1 tsp sugar to 2 l of water.
- Should the bottle left untouched, or it is useful to shake it occasionally?
- To keep it warm, is it good to put it in sunshine, or a dark place is better for it?
- Leaving air in the bottle or filling it completely?

I agree with @SAJ14SAJ. What I would add is that
yeast does not require sunlight in any way ... but as UV light can be harmful to microorganisms and might inhibit yeast growth I wouldn't brew it in direct sun.
for bottling beer it is normally suggested to leave the correct amount (1 - 1 ½ inch) of headspace (air) at the top of the bottle for carbonation and proper pressure. But I am not sure if the same conditions apply for soda - I would think it is not too different.
shaking gently occasionally might help to evenly distribute the yeast in the sugar solution, and expose it to more food resources (sugar).

Can you make soda with yeast?
The yeast consumes the sugar in the soda and converts it to carbon dioxide (and technically, a teensy-weensy bit of alcohol, but not enough to worry anyone - keep reading for more on this). For the best bubbles, you'll want to use champagne yeast. Using baker's yeast or brewer's yeast will produce a less-bubbly brew.Can you make soda with bread yeast?
You can use the standard bread yeast if that's all you have, but yeast specifically designed for brewing will turn out much better. You can use wine yeast, but DON'T use a lager yeast \u2013 it can over-carbonate your soda and lead to exploding bottles.How do you make soda water with yeast?
Dissolve the yeast (I used less than 1/8th of a teaspoon per batch) in warm water and 10 minutes later add a small amount of the flavored syrup. Let this sit for 20 minutes more and then add everything to your juice. Pour everything into a clean 2 liter soda container and put into a cool dark place for 48 hours.Is yeast used to carbonate soda?
Carbonation happens when yeasts are eat sugar and turn it into carbon dioxide. When the carbon dioxide is contained, like in a bottle, the carbon dioxide builds up and turns into bubbles.Creating Artisanal Sodas with Yeast

Answer 2
There are many resources on the web for home brewing soda, which you may wish to google.
Of your specific questions, the only one I was able to find a clear answer to is that the fermentation temperature should be on the order of 70-80 F / 21 - 27 C, per Home Brewing.Org.
There is no mention in any of the articles I have seen of turning or shaking the bottles. Similarly, none of the ones I surveyed mentioned fill depth; common sense would indicate filling to within an inch or so (2 cm) of the shoulder of the bottle, as is typical.
For safety, do not do this with glass bottles. There is a risk of explosion, broken glass, and of course, sticky mess.
