Particles (either of algae, bacteria, or waste) that cloud the water are too small for most conventional filter pads to collect, as they are more intended for larger waste. First one must determine the root cause of the cloudiness to properly treat the condition. Easiest way is to determine color, length of tank operation, recent changes to decor, inhabitants or other factors.

clear, if your water is cloudy then you might want to check your filter
Your tank filter should be changed every month. If your filter becomes clogged, it should be changed right away.
clean the tank, go to the pet store and you can find fish tank cleaners. just make sure you dont suck up the fish
No, because they will die!
no its not okay
You can : -Use prime, its a chemical which stops ammonia and nitrate. - Stop feeding the fish for a couple of days in order to let the filter cycle - go to the fish shop and buy some good bacteria to put inside your tank to make it cycle. Don't: -clean the filter

Yes it is inhumane to keep any fish in a tank without a filter if you do not want to put the effort into changing the water frequently. Fish can be kept without if the water is changed regularly, but maintaining the correct water parpmeters is hard. As they will die if the water is not changed regularly a filter must be used if you don't want to put as much time and effort in. IT IS EASIER TO KEEP FISH IN A TANK WITH A FILTER THAN ONE WITHOUT
Filter a fish? Do you mean filtering a fish's tank? Well you have to filter any fish's tank.
They should not turn cloudy. If yours does, then you must be doing something wrong. Is your gravel cleaned properly? Have you allowed more than 1 gallon of water per 1 inch of fish? Is your filter properly cycled and operating efficiently? Is the tank at the right temperature for the species of fish it houses? Have you been replacing at least half of the water weekly? If the answer is "No" to any of those questions, you will have the reason for the cloudyness.
No it's not a bad thing, as long as the filter is not too strong. If the filter is too strong it could make it difficult for the fish to swim around. It is also not usually necessary to use a filter with a betta, as long as the water is changed about once weekly. A filter would probably lengthen this time, but would NOT eliminate it.
Yes it does.
