Hi, I have one L3 Cisco Switch and I have configured sub interfaces and assigned V-lans like 1,2,3,4 and 5 and using only one interface e0/1. Now the connection between e0/2 and FW wud be a Trunk. Thanks!!

You don't use subinterfaces on a l3 switch .It would be configured something like this.
interface gx/x
switchport trunk encapsulation dot1q
switchport trunk native vlan X
switchport mode trunk
switchport trunk allowed vlan X
