We Can try like this 
trigger AccountTrigger on Account (before delete) {
   genricClass.AccountMethod(trigger.old);
}
//------------------------------------------------------
trigger ContactTrigger on Contact (before delete) {
   genricClass.AccountMethod(trigger.old);
}
//------------------------------------------------------
trigger Cycle__cTrigger on Cycle__c (before delete) {
   genricClass.AccountMethod(trigger.old);
}
//------------------------------------------------------


public class genricClass{
public Static void AccountMethod(list<Account> lstAcc){
 set<String>OwnerId = new set<String>();
    boolean deleteflag = false;
    for(Account Acc : lstAcc){
        OwnerId.Add(Acc.OwnerId);
    }
    list<User> lstUser = [select id,Delete_Records__c from user where Id In:OwnerId And Delete_Records__c = true];
    if(lstUser.size()> 0){
        deleteflag = true;
    }
    for(Account Acc : lstAcc){
        if(deleteflag == true){
            Acc.AddError('You Cannot Delete Record');
        }
    }
}
//------------------------------------------------------
public Static void ContactMethod(list<Contact> lstCon){
 set<String>OwnerId = new set<String>();
    boolean deleteflag = false;
    for(Contact Con : lstCon){
        OwnerId.Add(Con.OwnerId);
    }
    list<User> lstUser = [select id,Delete_Records__c from user where Id In:OwnerId And Delete_Records__c = true];
    if(lstUser.size()> 0){
        deleteflag = true;
    }
    for(Contact Con : lstCon){
        if(deleteflag == true){
            Con.AddError('You Cannot Delete Record');
        }
    }
}
//------------------------------------------------------
public Static void CycleMethod(list<Cycle__c> lstCycle){
 set<String>OwnerId = new set<String>();
    boolean deleteflag = false;
    for(Cycle__c C : lstCycle){
        OwnerId.Add(C.OwnerId);
    }
