As per your license restriction. you can have one inside and one outside and one failover interface for one ASA & other ASA you can create 20 nameif's if am not wrong. Check for someother trail license to match 20 VLAN's like the other ASA and use it if required.
Something is not right with your outputs. If your Cisco ASA 5505 has Security Plus license, you should have 20 VLANS enabled, and NOT 3. Where did you get these trial licenses from? This is because, Cisco doesn't give trial licenses for Security Plus license.
The basic license allows only 3 active VLANs which you can use as Inside, Outside and DMZ. However, there is a restriction here that many people do not know about: The DMZ VLAN can access ONLY the Outside VLAN but can not access the Inside VLAN. The other two VLANs (Inside and Outside) can access all the other VLANs with no problems.
-->>> VLANs : 3 DMZ Unrestricted
The Security Plus license, removes all limitations and allows up to 20 active VLANs to be configured. Since there are only 8 physical ports, you can create several vlan subinterfaces on each physical port to segment your network into different security zones (e.g Inside, Outside, DMZ1, DMZ2, Sales, Engineering etc).
-->>> VLANs : 20 DMZ Unrestricted
The ASA5505 can only perform Active/Standby failover and not Active/Active. In fact, ASA5505 don’t support Stateful Failover (meaning all active connections will be lost after a failover event).
P/S: If you think this comment is useful, please do rate them nicely :-)
