Hello,
What is the maximum number of neighbor relation that we can declare in 4G-5G and 5G-5G in NSA and SA?

4G to 5G I think 32 per 4G cell.

32 by freq? Its so little?
Is it for all vendors?

Yes, as of now less on top of it need to defined manually no ANR.
For 5G to 5G I will check limit.

ANR is working between 4G and 5G.
