Do you think Singapore's economy will survive?

This is a very good question which I think is worth answering more in detail with a macro and mirco economics way of looking at this.

In the long run, yes I am confident that the Singapore economy will survive given our history in battling recessions and downturns.

However along the way in the short run, I do think that many companies will get injured along the way, many will die, and people left jobless as well.

As harsh as it sounds:

Yes why not! Singapore economy can survive in all conditions. As per Vivian Balakrishnan, minister-in-charge of the Smart Nation initiative - Interdependence is key to Singapore's economic survival.
