Interface GigabitEthernet1/46- 1/48 are fiber points coming in off my Fiber equipment.
INT GIG1/1- 1/4 are going back to my Layer 3 Swtich. The fiber company wants me to give each customer its own VLAN - I know what to do for the Fiber ports (1/46-1/48 is just keep adding Addtional Vlans IE: switchport trunk allowed vlan 84,85), But I don't want to use any more then port 1-4 back to my Layer 3)
As you see I have 1 Vlan Assgined to each port back to my Switch.- How do I change that?

You should be able to add vlans to the trunk connecting back to the layer 3 switch
switchport trunk allowed vlan add
HTH, rate if it does

yes it should work. you need to allow the vlans on trunks on both sides.
Can you post a simple network diagram
