If one heard Barachu (by shachris) and davened shemonei esrei but didn”t hear kedushah can he be pores al shema and get kedushah by repeating shemonei esrei with ten? Does he also need to complete the pores al shema shemonei esei? What is also the halacha by mincha?
One who has already davened should not repeat Shmone Esrei with Pores Al Shma.
While the opinion of Shulchan Aruch is to permit this [O:C 69:1], see the MIshna Brura there s”k 1, that the halacha follows the Radvaz and many others who prohibit this practice.
