1. Yes. Just make sure everything is clean / sanitized. The more often you open/close the foil lid the higher your chances of getting contaminated. (your better off making a really large starter if you want to pitch some to your wort and save the rest.)
2. Yes. Yeast that have a really low Flocculation I leave maybe 1-2mm of starter to swish around the flask with. Yeast with really high Flocculation I leave maybe 3-5mm. Doesn't have to be exact. You will get the feel for it after a few starters. Swish > pour > swish > pour...
3. Yes. Some brewers will wash the yeast from a fresh 5gallon brew and divide the washed yeast into 4-6 quart jars and store them. They then open a jar to make a new starter for each batch afterwards.
4. Yes and Maybe. I generally decant a large portion of the spent wort/beer before I pitch my starter into my wort. But when I first started brewing I just pitched the whole thing in. Never had a problem. In theory the amount of starter to wort is marginal so it shouldn't effect the taste. But its totally up to the brewer.
