Various Masaail on Qadha Salaah

Q: I woke up with my alarm fajr time then I saw that there was some time for Fajr salah to end. So I decided to sleep for some time or close my eyes for some time then wakeup and pray Fajr salah but when I closed my eyes I was getting too sleepy so I said to myself and also thought that if I close my eyes or sleep for some time Fajr time will be over but my intention was to pray salah on time. So later I woke up after the time was over...

I was so sad that I woke up after the time finished. This happened for the first time with me and it was never my intention to miss the salah. After waking up after the was time over, I prayed Fajr so is my Fajr valid?

I am so worried. I was sure that if I will sleep I will wake up after Fajr time but my intention was to wake up and pray in time and I slept to get up after some minutes but unfortunately I didn't wake up. I never wanted to miss the salah.

Q: If a male becomes baaligh by having wet dream and ghusl becomes fardh on him, but he doesn't know that in Shariat you have to perform ghusl after having a wet dream. So he keeps praying with just making wudhu and after 3-4 months of his puberty, he comes to know that ghusl becomes fardh by wet dream. So are all his prayers in these 3-4 months counted or does he have to make qadha?

While offering these prayers again will he make intention of praying qadha prayer or will he make intention of repeating the prayer (I'adah)?

Q:

1. My menstruation cycle is regular in the sense that I have 14 clean days, 1 day istihaza and 10 days haiz. It's the same every time. So it starts at 4.43pm. I am usually always alert about performing my asr salaah before the time of haiz starts. Unfortunately today I was unwell earlier and had to sleep and over slept and only awoke after the time of haiz began. Will this asr Salaah be considered as qaza?

2. As a saahib tartib if I make ghusl and I have only enough time to perform the fard salaah and not the qazaa. When do I read the qazaa?
