GS308-3 adding a second ethernet switch FS105 with jumper

[DM56]

Can you use a jumper to stack two switches? Netgear 8 port with 5 port added with jumper cable. Home application, ran out of ports on the GS308. want to add FS105 switch for the additional ports.

not sure what you mean by jumper. 

You can connect 2 switches together with an ethernet cable. I've got multiple switches

If "jumper" means a straight instead of a standard crossed (X) cable the answer is no. Modern switches have a feature called Auto-X.
