Glad to hear that your new geckos are settling in. Geckos are quite resilient and most resume normal activities very quickly.
I think you will have good success with either a 1:1 or 1:2 ratio for breeding. Personally, I usually go with 1 male and two females but I don't know that having more than one female stimulates activity. Just put them together and you will have babies before you know it.
Also, you should be aware that gecko mating can be pretty violent compared to that of snakes. Nothing to worry about, just don't be surprised.
