Can some one help me create a trigger for auto creating 5 child records when parent record stage is closed

Question

Hi I tired creating below trigger but it is giving me this error:

Loop variable must be of type CSM_Milestone__c

trigger CSMMilestone on CSM_Milestone__c (After insert, After update) {

     List<Opportunity> oppList = [select Id from Opportunity where StageName = 'Closed: Won']; 

     list<CSM_Milestone__c> csmList = new list<CSM_Milestone__c>();
     for(Opportunity o : trigger.new)
     {
        CSM_Milestone__c csm = new CSM_Milestone__c ();
       // quote.Opportunity = o.id;
        csm.Name = 'CSM Milestone1'; 
        csmList.add(csm);
        if (o.StageName == 'Closed: Won'){
           for(Opportunity act: oppList){
              csm = new CSM_Milestone__c(Name='testName');
             // quote.Opportunity__c = o.Id;
              csmList.add(csm);
           }
        }     
     }
     insert csmList;    
}

This is sample code to create object in opportunity. In for loop you can give your logic to create your records same like opportunity

trigger CSMMilestone on Opportunity(After insert, After update) {

list<Opportunity> csmList = new list<Opportunity>();
 for(Opportunity o : trigger.new)
 {
    // if you want to create record in opportunity
    if (o.StageName == 'Closed: Won'){        
    Opportunity csm = new Opportunity();
     csm.Name = 'CSM Milestone1'; 
    csmList.add(csm);
    }     
 }
 insert csmList;    
 }
