you can have multiple
<c:if>
and for the case of no notification, you can have something like
<c:choose>
<c:when test="${formObj.msgCount == 0}">
"Here comes your no notification message"
</c:when>
<c:otherwise>
Multiple <c:if></c:if> conditions
</c:otherwise>
</c:choose>
It should handle your use case.
