Want to keep them indoors, they are under mostly under 1 to 2 feet tall. I want to avoid dormancy, but a few, already lost all their leaves. Should I just put them in the cold washroom to complete the dormancy stage or bring them indoors by the window and they can hopefully restore their leaves and continue growing.....Thank you in Advance.

Armando if mine i would let them little Gals go dormant but then again im not in California.
Here in our zone loseing leaves and trying to stretch things just is not wise as i feel its a strain on a plant
especially on young one.

Fully agree with Martin.
Plants feel the onset of fall in most climate that naturally triggers the dormancy by shedding leaves and going into rest period, longer or shorter period depending on the location.
Let the plant follow the nature routine and it may be more happy to please you when it wakes up to start bud swelling.

"Dormancy" is a systemic event in plants.  If the plant already has some leaves changing color and dropping off, the systemic changes have already started (even if it seems to be leaf - by - leaf), and just moving the plant into a warmer environment should not stop what has already started.

Thank You for all the Information.......It has helped a lot......have to many small trees and many in cups.....don't want to create Humidity and mold in my home.
