Native VLAN 5 and ACCESS 10 will not establish trunk, and VLAN's 5 and 10 will be interconnected. I.E. Users from VLAN 5 on one switch will communicate with users in VLAN 10 in the other switch.

NATIVE vlan 5 and ACCESS vlan 10 means that frames for those VLANs are sent untagged, therefore as normal ethernet traffic in a broadcast domain.
