I don't think it's a good way to learn chinese. cas, we haven't the same logic of speaking. so, the best way is you know " 他们什么时候能理解我？" = "when the hell can they understand me?!" it's enough, it's ok. you've got the model sentence. so,她什么时候能理解我？= when can/will she understand me? 我什么时候能理解你？= when shall/can I understand you? 我什么时候能吃饭？ = when shall/can I have the dinner? I'm sure you've know what I meant.
