I have created 4 triggers that I merged into 1 trigger for "best practice." The trigger ​works very well in the sandbox but I don't believe I have merged the triggers correctly. Any assistance or suggestions to help me merge these triggers correctly is greatly appreciated!

Merged trigger below.

trigger SurveyHandling on Relationship_to_Initiative_Research__c (after insert,after delete,after update) {

        list<Id> rlist1=new list<Id> ();String sss='';
        list<Initiatives__c > rlsit=new list<Initiatives__c >();
