I need following parameters for my NOMA-5G implementation.
1.Maximum number of users in a cell (Radio capacity)
2. Spectral efficiency in terms of (Erlangs/MHz)/m2
please provide any formula to calculate spectral efficiency
3.Frequency reuse value
It depends on the scenario and application you are trying to simulate. As already mentioned, no public networks are using NOMA right now.
You can find some trials performed by NTT DOCOMO here.

In uplink direction in massive MIMO based 5G systems, users are approximately seperated (tanks to favorable propagation), hence the "multiple access' concept makes no sence in this context therefore NOMA makes no sense as well
Dear Taherbasha
I would like to pay your attention to the possible use of NOMA supported MIMO systems for the 5G to increase the spectral efficiency. Please refer to the paper in the link: https://arxiv.org/pdf/1808.00277.pdf
Best Wishes
Let's assume 5G is enhanced by NOMA, how that affects spectral efficiency and user capacity per cell? The answer is of a statistical nature as there are many trade-offs involved, so there is no single number to answer your question. CDFs are best to explain such trade-off between number of users per cell and achieved spectral efficiency. One interesting research article you can refer to as a start is https://metis2020.com/wp-content/uploads/publications/IEEE_2013_Benjebbour_etal_DownlinkNOMA.pdf
I don't know of use of NOMA in 5G for now but development is dynamic and anything could crop up at anytime. 5G is still in its early stages of use and there could be improvement with on going researches
