Should the laptop be ok to be charging over there on 110v.

yes

If shaver is 240 volts only would it run but slower.

I'd expect it to be more like a rough plucking, than a shave

Also for charging phones will they charge but at a slower rate.

Should just take more current from the mains (or take it for a larger
fraction of the mains cycle) and charge the same.
