Is it OK to:

1) ask a Jew who isn't particular about Shabbos to turn off a light?

2) ask a non-Jew to turn your light on?

3) ask a non-Jew to turn your annoying alarm off?

4) ask your non-Jewish cleaner to clean up from Shabbos?

5) ask your non-Jewish cleaner to set up for Saturday night event? 

6) plug in your freezer which is full of meat when the plug got knocked out?

7) ask a non-Jew to bring you Challah from your neighbor when there is no eruv when you realise on Shabbos that you have run out of Challah?
