You can only have one chain at the time. You can, however, create your custom URP chain to contain configuration from all three.
Or, if you do use multiple chains that are configured similarly, you can pull each URP into its own definition and then mix and match then either in the chain or even per request (or in request defaults): https://lucene.apache.org/solr/guide/8_5/update-request-processors.html#configuring-individual-processors-as-top-level-plugins Regards, Alex.
