Cisco vlan trunking
I have a core switch connecting to 13 edge switches. It switxh will connect to the core directly.
The core has 15 vlans for the switches to access the vlans do I need to make all the ports on the core members of the same trunk?

13 separate trunks or 1 trunk?
If you have a core switch (master) and 13 switches (clients). You need to give a link from the core to each switch.
You don't want to daisy chain btw switches.

OK let me explain.
I have a 2 core 3850 switches stacked. Each edge switch has a LAG configured with 2 ports. 1 port connects to one port on the core and the other to one port on the 2nd core.
Do I create a trunk per switch? or can I create one trunk and all ports on the core into it.

You got it.

does it matter if there are multiple channel-group with the same name?
You create the Trunk on the LAG/port-channel not the uplink!

CORE SWITCH:
Configure the 13 ports to become TRUNKS.
Switches:
Configure each port of each switch to become TRUNKS.
If you are using VTP, configure the client switch to receive the vlan information from the CORE.
In case you are not using VTP make sure you have created the vlan in each switch.
