Is it true that there is a Hadith stating that the first to be held accountable is Umar ibn al-Khattab, may Allah be pleased with him, and how will he be held accountable when he was martyred?

This hadith is weak and not authentic. It states that the first person from this Ummah to be given his book in his right hand is Umar ibn al-Khattab, and that he will have a radiance like the sun. When the Messenger was asked about Abu Bakr, he said: "The angels escorted him to Paradise." This hadith is not authentic, and the one accused of fabricating it is Umar al-Kurdi, the liar who invents hadiths. Moreover, despite its weakness, the hadith does not mention Umar's accountability.
