Qadha and Kaffara

Q: If one breaks his fast for "sports" activities, will qadha or kaffarah have to be kept?

Q:  

1. Prior to 1 year earlier, I did not know that masturbation breaks the fast and I used to do it in the state of fasting. Do I still have to make qada even if I did not know it at that time?

2. If yes, how should I calculate how many fasts I should make qada for? I am not sure how many of my fasts were broken like this. How many qadas should I make if I did not know this for 5-6 years after becoming baligh?

3. Should I make qada for all the fasts for the past 5-6 years or is there a specific number I can keep to make it alright?

4. Am I obligated to keep all the qada fasts together or can I keep them once or twice a week?

Q: If a woman has one qadha fast to pay in. She has sehri and begins her qadha fast, later in the day her haidh begins. Is she required to fast 2 days now, because the qadha fast broke or fast one day?

Q: What do the scholars say regarding A woman who fasts during Ramadhaan.

Ss she committing sin by this act? Please give guidance.

Q: If a person masturbates in Ramadhaan while fasting, should he give kaffarah or keep qadha?

Also, what should one do if he has doubt as to how many times he committed this heinous sin? Should he think of a reasonable number and pay kaffarah/keep qadha for that number of days?

Q: Last Ramadhaan I indulged in a major sin unknowingly. One day I was not well and I had not fasted on that day and I had sex with my wife during the day not knowing that whether you fast or not you cannot have sex in the day. Please suggest what to do now.

Q: I'm replacing my qadha fasts. I fasted for five days consecutively but sometimes I forget to make the intention although I know that I'm replacing my qadha. Should I fast again for the days that I didn't make intention verbally?

Q: If one has qadha fasts to still keep, can one keep nafl fasts or do you have to keep the qadha fast first?

Q: Can one fast the 6 days of Shawwal as your fard days that you have to pay in together or must it be separate?
