1-Where are the Tablets of Prophet Moses, peace be upon him, now?

This question does not lead to action, and it is better for a person to occupy themselves with what benefits them. The Quran and Sunnah did not address the location of the tablets. It is mentioned in the Hadith that Musa (peace be upon him) did not cast down the tablets when Allah informed him of what his people had done with the calf. When he witnessed what they had done, he cast them down, and they broke. It is also mentioned that the Prophet (peace and blessings of Allah be upon him) was given seven of the long surahs (the المثاني الطول), and Musa was given six. When he cast down the tablets, two were raised, and four remained. For more information, one can refer to books of Tafsir (exegesis) for verses 145 and 150 of Surat Al-A'raf.
