res_pjsip.c uses a threadpool to distribute the work that it does. Some 
users of res_pjsip.c require that their work be handled in sequence, so 
they use serializers in order to group these tasks together. For 
instance, res_pjsip_session.c creates a serializer for each SIP dialog 
that it creates. This way, tasks pertaining to the dialog are handled 
serially, and there are fewer concurrency concerns regarding data scoped 
to the dialog.

Serializers, internally, use an ast_taskprocessor in order to do their 
duty. Serializers created using the ast_sip_create_serializer() function 
use a UUID [1] to name their taskprocessors. The output that you have 
pasted shows many taskprocessors with UUIDs as names, which likely are 
all serializers in the SIP stack.

I hope that answers your question.
