Can a strict believer in God, His Books, His Angels, His Prophets (Alaihi As-Salaam) and the Judgment Day who always does good things and prays, fasts and recites the Qur'an regularly and who does Du'a and who is kind to the people see the Prophet Muhammad (Sallallahu Alaihi wa Sallam) in the seventh heaven and live with him and his family (Radiya Allahu Anhum)? I know that Allah knows these things better than all the human beings in heaven or on earth, but perhaps you have some answers.

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

If a Muslim performs what Allah has imposed upon him, avoids what Allah has prohibited him to do and worships Allah faithfully and sincerely, then there is hope for him to have a good in this life and good in the Hereafter.
So, Allah will raise high his fame in this life and He will make him with His righteous slaves in Paradise in the Hereafter.
The best and highest degree for believers will be with the company of the Prophet (Sallallahu Alaihi wa Sallam).
Allah Says (interpretation of meaning): {And whoso obeys Allâh and the Messenger (Muhammad SAW), then they will be in the company of those on whom Allâh has bestowed His Grace, of the Prophets, the Siddiqûn (those followers of the Prophets who were first and foremost to believe in them, like Abu Bakr AsSiddiq radhiallahu'anhu), the martyrs, and the righteous. And how excellent these companions are!} [4: 69].
Attaining high ranks in Paradise is achieved through full and complete obedience to Allah, i.e. to do what He orders, to believe in what He states and to avoid what He bans.
Here are some actions that bring one closer to the Prophet (Sallallahu Alaihi wa Sallam) in Paradise:
1 - Taking care of the orphan: The Prophet (Sallallahu Alaihi wa Sallam) said: "I will be like this in Paradise with the person who takes care of the orphan". 'Allah's Messenger (Sallallahu Alaihi wa Sallam) raised his forefinger and middle finger by way of illustration'" . [Reported by Imam al-Bukhari ].
2 - Educating daughters and sisters well. The Prophet (Sallallahu Alaihi wa Sallam) said: "Whoever has three daughters or three sisters, fears Allah concerning them, educates them and takes care of them, will be with me in Paradise" . Allah's Messenger (Sallallahu Alaihi wa Sallam) raised his four fingers. Imam Ahmad in al-Musnad, and al-Sheikh Shu'aib al-Arnaaut regarded it as sound.
3 - Revival of the Prophet's (Sallallahu Alaihi wa Sallam) Sunnah. The Prophet (Sallallahu Alaihi wa Sallam) said: "Whoever revives my Sunnah, loves me; and whoever loves me, will be with me in Paradise" . al-Tirmizi from Anas .
Allah knows best.
