1. "I cannot gurantee (guarantee) that the delivery should be on time"
2. "I am not able to gurantee that the delivery will be on time"

It should be on time means that it will likely be or that it ought to be, which already implies that it is not guaranteed.

1. It would be correct to say: "I cannot guarantee that the delivery will be on time." You could also say,

"The delivery should [ought to, will likely] be on time, but I cannot guarantee that it will be."

2. Okay
