Hi Hemant,
Thank you for using Syncfusion products.
It is possible to open multiple document's. This is done using "WordDocument" interface. Using object of "WordDocument" the document is opened and saved. This is done by using following code snippet.
[C#]
WordDocument document = new WordDocument(@"..\..\Sample_Doc.doc");
document.Save("Sample.doc");
document.Open(@"..\..\Sample_Doc1.doc");
document.Save("Sample1.doc");
Here is the sample program for your reference.

C:\Documents and Settings\{UserName}\My Documents\Syncfusion\EssentialStudio\5.1.0.51\Web\docio.web\Samples\2.0\Interactive Feature\
Please let me know for further help.
Regards,
Sarath
