Assalamu Alaikum
There are 5 obligatory prayers in the day:
1. Fajr (Done at Sunrise)
2. Dhuhr (Done Early Afternoon)
3. 'Asr (Done Late Afternoon)
4. Maghrib (Done at Sundown)
5. Isha (Done in Evening)
There are specific times at which these prayers have to be done because it depends on the location of the sun. Therefore, you can use islamicfinder.org to enter your location and find out the specific times the prayers should be done.
Essentially all the prayers are prayed similarly except the number of rakaat is what differs. A rakaa basically means how many courses of movements is to be done in a prayer.
So for example, Fajr requires 2 rakaat, dhuhr is 4, 'asr is 4, maghrib is 3, and isha is 4.
Before every prayer you have to be in a state of purity, so you have to perform wudhu (cleansing ritual/ablution) anytime you use the bathroom, pass gas, or come into contact with anything impure (such as urine). Ghusl (full body bath) is to be done after intercourse or if you're a female, after you complete your period/menses (you can't pray while you have your period/menses).
This is how wudhu is done:
You can use these youtube vids which highlight exactly how to do each movement for each prayer and what to say:
Fajr
Dhuhr
Asr
Maghrib
Isha
Before making wudhu, ghusl, and salaah always remember to make the intention in your heart first.
If you memorize the following it will make it so much easier on you: Al Fatiha,
Tashahhud,
Salah ibraheemiya
And of course if its difficult for you to memorize everything, you can always write down the words on a paper and use it as you do the movements until you can recite without the paper. If you have any other questions (I know it can get overwhelming) feel free to ask! :)
