Wa Alaykum Assalam SisterI
Congratulation on your convertion , may Allah accept us as Good Slaves and grant us guidance and happiness in both lives.
I was little bit confused when you stated that you are the only muslim here !! where in Kuwait!! but when i read your post again it seems to me that you are In a closed Unit! right? the Army? WOW! subhan Allah.
Its up to you you can recite more than one surah , one or more its OK.Do you only recite one Surah and then go to perform your bow and prostration? or do you recite more than one Surah?
No, for each time you stand you should recite Al-fatiha once then recite whatever you want to then go to perform your bow and prostration. and then stand up again to do the same as you did in the 1st time. after the 2nd prostration. sit and recite the Tashahod then finish your prayer like any prayer with Assalam Alaykum wa rahmatullah right and left.Do you recite the Al-Fatiha Surah before every recitation of different Surahs?
do the same as you did for 4 times with different surahs if you want.. so the total are 8 Rak3a , its not obligatory to pray Taraweeh or to pray a definite number of raka3at (plural of rak3a).
after that you can pray three rak3at with intermediate Tashahod or without (both are OK) this prayer is Called witr, the tanslation of the word witr is (odd which is contrary to the word EVEN ) even in arabic= Shaf3...
and 3 is an indication for an arabic letter which you don't have a similar letter in english .. you need to hear it from some arabs and you have many in Kuwait..
now the total numbers of Raka3at are 11.. GOOD?!
may Allah accept from you sister and choose you to pray well in Ramadan specially in the last 10 days specially on that night called (laylat Alqadr) which is better than (Alf shar) = better than 1000 monthes.
in which the revelation of the Quran started from more than 14 centuries .
jazaki Allah khairn and may allah accept from you your prayers and your fasting
I advise you to ask some elder sisters ( pick a knowlegable one) about the fasting conditions for women as its your 1st ramadan.
Assalam Alaykum wa rahmatullahi wa barakatuh
