Q&A for How to Wear a Pancha Kachcham

If the dhoti is "double" (8 or 10 yards), then you must make a single folding so that it becomes exactly half of its full length and its original ends come together. If it is "single," no folding is required. Wrap it around your waist, leaving equal length at both sides but ensuring that the original end portions are on your left side and the folded end on the right. Bring the right portion up to your extreme left and tuck it there tightly. Then take the left portion over the right one and bring it up to the right end and insert it there tightly.

No, you just fold it on your knees.

Not necessarily, but that is the best way to prevent yourself from a wardrobe malfunction. Wear a short that isn't visible when the dhoti is on and choose a light colored short.

At Indian/religious ceremonies, it's okay, but some establishments have a "No shirt, no shoes, no entry" policy.
