yes
Small insects such can walk on water because their weight is not enough to penetrate the surface. A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, needle will quickly sink.
Low surface tension means high wetting as it represents low contact angle. It is therefore very easy for a low surface tension water / liquid to wet the surface ( usually solid) and get rid of the dirty in a same way a surfactant does unlike a high surface tension liquid which can't wett the surface containing the dirty....

Yes a paper clip is able to float in water. Take a bowl, fill it up to the top with water, take a paper towel and put it into the bowl, let it sit there for 3 seconds...then put the paper clip on it, and slowly remove the towel. This is able to work by Surface tension.Depending on the size, some paperclips can due to the high surface tension of water.
Pulmonary surfactant...see link for more information.
Yes, if its in the right form.Related Information:Just about any substance can be made to float on water by displacement. Extremely small masses can also be supported by the surface tension of water. Depending on the mass and form, graphite can do either.

The surface tension of the water stops it from breaking the surface so long as it does not cut through it. The irregular shape and weight of a metal ball made from the same thing cuts the surface tension and breaks the electronic bond that exists between the water molecules at the surface.
A coin can float on the water under a couple of circumstances. The most obvious is if it is made of a material lighter than water. And the second is if it is broad enough that it can be laid on the surface (carefully) and in such a way that the surface tension is not broken.

surface tension is simply liquid (usually water) molecules that join together and creates an invisible "skin" around the top of a glass when you fill it to the top very slowly and it goes over the brim but doesn't spill. surface tension is made by cohesion.

Well, I know this because I played with bubbles when I was 6-9 so yea. Bubbles are made of soap, but with air inside of that bubble. Bubbles are things that come in contact with solid will disappear or pop.
The winds from a hurricane blowing across the water's surface creates waves. The stronger the wind, the bigger the waves. Put some water in a bowl and blow across the surface. You made waves.
Bubbles cannot just be made with plain water; you need to add soap or something else like that. Shampoo, bubble bath, soap etc...
