Are you talking about secondary interfaces on an SVI?

Not sure about the exact number, but you can a lots of secondary ip addresses. Not a very common deployment though.
have a look:
interface Vlan1
ip address 2.2.1.2 255.255.255.0 secondary
ip address 2.2.3.2 255.255.255.0 secondary
ip address 2.2.4.2 255.255.255.0 secondary
ip address 2.2.5.2 255.255.255.0 secondary
ip address 2.2.6.2 255.255.255.0 secondary
ip address 2.2.7.2 255.255.255.0 secondary
ip address 2.2.8.2 255.255.255.0 secondary
ip address 2.2.9.2 255.255.255.0 secondary
ip address 2.2.20.2 255.255.255.0 secondary
ip address 2.2.30.2 255.255.255.0 secondary
ip address 2.2.40.2 255.255.255.0 secondary
ip address 2.2.50.2 255.255.255.0 secondary
ip address 2.2.60.2 255.255.255.0 secondary
ip address 2.2.70.2 255.255.255.0 secondary
ip address 2.2.80.2 255.255.255.0 secondary
ip address 2.2.90.2 255.255.255.0 secondary
ip address 2.2.100.2 255.255.255.0 secondary

I think we had the same type of question earlier but not able to search that thread.
I dont think there is any limit define as such in any document on configuring the secondary ip address on the svi.
Will do search again and get back on this.

How many secondary network config possible???
Depends on how confused do you want to be and how confusing do you want your network to become.
Rule of thumb in regards to secondary IP address: DON'T.
