According to https://hub.qgis.org/issues/15265, the GDAL tools might get lost if you have the processing tools installed as an external plugin.

Based on your question, I would do several extract by attributes and then merge the extracted together. This can be done in one and the same moddel. But to be sure, you have to be more specific about what algorithms you are using to break them down.
