Young man grew up in the worship of Allah

salam
1.if a muslim has been brought up in the worship of Allah (i.e. worships Allah sincerely) starting at the age of 15 and up to his adulthood (30 & above), is he included
among those 7(the youth) who will be given shade by Allah on the Day of judgment?

2.if so, then for example if that muslim practiced some form of riya,vanity,conceited etc.. at the age of 23 then sincerly repented at the age of 28, will he still be
counted among those 7(the youth) who will be given shade by Allah on the Day of judgment?

jazakallah khair.
