My game currently runs a level with using about 20 to 30 MB of System memory and the texture memory is between 160 and 200 MB.
Is this a normal range which should run fine on all devices?

Those figures do seem quite high, but it also depends on what kind of game you are game you are working on.
For reference, the largest game that I've worked on to date with Corona tops at around 8MB of system and 50MB of texture memory used when the @4x assets (largest available) are loaded.
At the memory usage that you've mentioned, I would expect you to run into issues with low end android phones and older non-high end devices.
