With nagios 4.0.8 installed on one machine with Centos 7 minimal, with no GUI, 1GB RAM and 160 GB Disk, how many routers, switches, servers can monitor with no problems?, and each switch with 5 services maximum, (bandwidth ports),
it can support 100 devices?

100 should be no problem, but there are many, many factors that affect this such as:
- CPU/core count
- Type of checks being run
- Frequency of checks
- % of hosts/services in a non-OK state
- # of notifications going out per problem
My advice has always been to build for more than you are expecting to monitor, and then add servers in groups while watching the utilization.

checks should be the ping, and for switches badnwidth for some ports, frecuency of checks the default, 5 minutes, the % of the states is often up

That shouldn't be too bad, is this a VM where you can expand at will?
