Sunni view on the Twelver Shia Imams? (Hadeeth request)
During a visit to Medinah I interestingly saw the names of the twelve Shi'a Imams (i.e. of the Twelvers, the mainstream Shi'a) —peace be upon them— with their reputations, around two saloons of the mosque of the holy Prophet —peace be upon him— (مسجد النبوی); before that I didn't know that the Sunni brothers also accept such reputations for the twelve Imams of Shi'a.
Note the green circles at top of the walls:
Those colored in green include 13 out of 14 innocents of the twelver Shi'ism (محمد، علی، حسن، حسین، زین العابدین، محمد الباقر، جعفر الصادق، موسی الکاظم، علی الرضا، محمد التقی، علی النقی، حسن العسکری، محمد المهدی علیهم السلام):

Are there any Sunni hadith that contains these names and reputations?
And although not necessary, it would also be helpful if such hadith would also address why the Twelver Imams are represented, but the Imams of other Shi'a sects are not (e.g. why Imam Kazim —peace be upon him— is considered here, but his brother Isma'eel is not).
