how to handle multiple namespaces with different URI in XSD
Short answer is you can't. You could, however, if you would be using three XSDs. It would allow you to have all the XSD that matters into one file (Chameleon.XSD), and have two more that simply compose Chameleon.XSD, those two having the namespaces you want.
Chameleon.XSD

Relationships:
If you want one XSD to validate them all, then you can go and build a fourth one, that imports these two.
OneAll.XSD

Updated relationships:
The end tags in second.xml need to match the beginning rags (i.e. soap does not equal saw)
