Is that possible to run the same classes byt replacing jre 1.5 with jre 1.7?

Unlikely
except the old code depends on the routines removed or vulnerabilities fixed in the newer runtime.
It is very rare that theyu remove any methoids in the older java - so in all probability it will run your classes compoilked with 1.5 just fine. Even if you compile your old code with newer compiler you mnay see. A lot of deprecated warnings, but in all probability ytour application will still run fine as those deprecated are disciouraged but not remvbed in the newer version of java.
It is more likely with GUI elements that something will not satisfy youi when you run it with newer java.n soi give it a try anyway.

2) gui related stuff would give problem?
3) as per the standards does all companies compile with new sdk, if they want to run with new jre?
4) I do not want to face the bad after effects of running old code with new jre, so please let me know your experience

On the other hand, if you have big applications and nothing presses you too much, I'd still wait a few months before moving to Java 1.7. Though I guess it is more than half a year as java 1.7 was released still I feel not that many people transitioned, it is only on update 3 currently - there may still be some details. Unless something presses you - I'd wait a few months maybe even half a year
