Hi Yefei, The OSG supports multiple render to texture Cameras seamlessly, it should simply be a case of creating the Camera's and adding the textures and appropriate subgraphs to them and then using these textures. The only twist would be that if you are using Viewer slave Camera then you'll need to make sure that these slaves don't inherit the main scene graph as is the default behavior of slave Camera. A render to texture Camera in the scene graph doesn't inherit any subgraph so it'll just use what subgraph you assign to it.
