Do I need the Atlas connector (#205) or the Twin (#210) in a stub-ended yard? I read that I need a SPDT for a yard, but someone else said the DPDT?
Also, could I use either one with a tortoise swtich machine? If so, how?
TIA!

Are you using DC or DCC?
The Connector is 3 DPST on-off switches. The Twin is 2 DPDT reversing switches. If you are looking for SPDT switches, you need the Selector #215. But remember the Atlas wiring components are designed for use with Common Rail wiring.
Tortoises could be controlled by a Twin, just run wires from the terminals at the top of the Twin to pin 1 and 8 of the Tortoise. The Twin's internal wiring will take care of changing the polarity of the control power.
If you use a bi-polar power supply (- + ground) you could use Selectors, by connecting the ground to one pin, and a wire from the top of the Selector to the other. You would have to supply the - feed to one side terminal and the + feed to the other.
It will work, but it's a rather ungainly way to do it. And depending on how many you need, at 10 buck a pop, the cost will add up quickly.
