ANSWER:

The prayer is valid as long as you fulfilled the conditions of salah, however it will vary in rewards, the more you have concentration and contemplation in salah, the more the reward. 

Whenever I offer Namaz, many memories come to my mind, then will this prayer be accepted?

How should we pray Taraweeh prayer at home in the coming Ramadan? Should we pray immediately after Isha? or Should we pray before FAJR? What should be our policy fr Taraweeh in coming Ramadan?

There are some narratives on performing Taraweeh at home. Since my childhood I understand that recitation of the Holy Quran is a must. So, can we recite several surahs during the 20 rakahs of this prayer during the month of Ramadan? Is it a Congregational or individual prayer?
