I'd like to setup a OpenVPN Server, connect multiple devices and have a software (database included) that can communicate with the devices that are connected on to the server. The software will be located in the same network.

Q1: How is the software going to communicate (send & receive data) with the VPN network IP addresses? If I give my OVPN devices IPs in the 10.0.0.0/8 subnet, will the software be able to communicate with all connected devices? My concern is that it will look for external IP addresses instead of the internals.

Q2: Will I be able to SSH for example, from OVPN Client A to OVPN Client B? (I will be enabling INTERNALNETWORK in my setup configuration)

Using whatever RFC1919 address you assign to your OpenVPN private network.

If I give my OVPN devices IPs in the 10.0.0.0/8 subnet, will the software be able to communicate with all connected devices? My concern is that it will look for external IP addresses instead of the internals.

You'll use RFC1918 addresses for all of your communication. The applications on either side of the connection have absolutely zero knowledge that this traffic is traversing an OpenVPN tunnel.

Will I be able to SSH for example, from OVPN Client A to OVPN Client B?

Sure, presuming you configure your firewall rules accordingly.
