You mentioned a very good point at the beginning of your question. Jinns can obey or disobey the commands of Allah (SWT). For the disbelievers (Kuffar) among the Jinn, they will be in Hell والعياذ بالله
Allah (SWT) says in Surat Al-A'raaf (#179)
And in Surat Hud (#119)
So, there is no doubt that the disbelievers (Kuffar), whether among Humans or Jinns, will enter Hell. For the sinners, Allah (SWT) will judge fairly, if He wishes to forgive them, He (SWT) will forgive.
Now, for the believers among the Jinns, the majority of the scholars have said that they will be admitted to Paradise according to various verses in the Qur'an that talked about Paradise, like this one in Surat Ar-Rahman (46-47)
Allah knows best!
