Yes, there are several Level of Jannah , as mentioned in Quran and Ahadees like:

1-“But for he who has feared the standing before his Lord are two gardens –So which of the favors of your Lord would you deny? –Having [spreading] branches…” [ar-Rahman 55:46-48].

and after that ALLAH says: “And below them both [in excellence] are two [other] gardens” [ar-Rahman 55:62].

2-Abu Sa‘id al-Khudri (may Allah be pleased with him) narrated that the Prophet (blessings and peace of Allah be upon him) said: “The people of Paradise will see the people of the highest places in Paradise above them as you see a brilliant star far away on the horizon in the east or the west, because of the difference in status between them.” They said: O Messenger of Allah, is that the status of the Prophets that no one else will attain? He said: “No, by the One in Whose Hand is my soul. They are men who believed in Allah and believed in the messengers.” (Narrated by al-Bukhari, 3083) and Muslim, 2831)

3- Sayyiduna Abu Hurayrah (radiyallahu ‘anhu) says that Nabi (sallallahu ‘alayhi wa sallam) said: “In Jannah there are one hundred levels. The distance between each level is a hundred years” (Sunan Tirmidhi, Hadith: 2529. Declared authentic by Imam Tirmidhi)

and there are many other narrations which make it clear that Jannah has many levels,
