Is there a way to know how many connections are established in a certain moment?. I know about netstat(1) but is there any other command that we can use to know the exact amount of how many connections are established?.

This one might help:

kern.ipc.numopensockets: Number of open sockets

It's usefulness will depend on the granularity you require (in only, out
only, established only, etc) but it's always represented system-wide
resource consumption very well (matching observed workloads - <some
baseline value>)
