1) Solution for 1 st error,

You have to add to, EmailCon, Email.. etc for testDObj,  before calling testDObj.sendpost(). Modify your test method as follows.


static testMethod void runTest1() {
       Account account = new Account();
       account.Name = 'Acc3';
       insert account;         
       Contact contact = new Contact();
       contact.FirstName = 'Todda';
       contact.LastName = 'Wilmss';
       contact.AccountID = account.Id;
       contact.Email = 'twilms@verisign.conm';
       contact.MobilePhone = '918527116723';
       insert contact;
              
        ApexPages.StandardController sc2 = new ApexPages.StandardController(Contact);
        apexpages.currentpage().getparameters().put('ID',contact.id);
        String  conId = ApexPages.currentPage().getParameters().get('Id');
        String  EmailCon =[Select email from Contact where Id=:conId ].email;
        sendmailexample testDObj1 = new sendmailexample(sc2);
        testDObj1.AddRecep='twilms@verisign.conm';
        testDObj1.to ='twilms@verisign.conm';
        testDObj1.EmailCon ='twilms@verisign.conm'; 
        testDObj1.Email ='twilms@verisign.conm';
        testDObj1.body='abc';
        testDObj1.subject='abc';
           
         test.startTest();
         PageReference pageRef = Page.sendmail; // Your page name
         pageRef.getParameters().put('Id', String.valueOf(Contact.Id));
         Test.setCurrentPage(pageRef);
        Test.setMock(HttpCalloutMock.class, new sendmailcontactmock());
          ApexPages.StandardController sc1 = new ApexPages.StandardController(Contact);//Instance of your object
         sendmailexample testDObj = new sendmailexample(sc1);
         testDObj.AddRecep='twilms@verisign.conm';
        testDObj.to ='twilms@verisign.conm';
        testDObj.EmailCon ='twilms@verisign.conm'; 
        testDObj.Email ='twilms@verisign.conm';
        testDObj.body='abc';
        testDObj.subject='abc';
          testDObj.sendpost();        
           test.stopTest();  
            
    }




2) Second error solution,

You have to pass Id parameter just befor line no 67.
 apexpages.currentpage().getparameters().put('Id',contact.id); 

You entire test class should be(Contains modified code for both error1 and 2 ),

@isTest
public class sendcontacttest{  
    static testMethod void runTest1() {
       Account account = new Account();
       account.Name = 'Acc3';
       insert account;         
       Contact contact = new Contact();
       contact.FirstName = 'Todda';
       contact.LastName = 'Wilmss';
       contact.AccountID = account.Id;
       contact.Email = 'twilms@verisign.conm';
       contact.MobilePhone = '918527116723';
       insert contact;
              
        ApexPages.StandardController sc2 = new ApexPages.StandardController(Contact);
        apexpages.currentpage().getparameters().put('ID',contact.id);
        String  conId = ApexPages.currentPage().getParameters().get('Id');
        String  EmailCon =[Select email from Contact where Id=:conId ].email;
        sendmailexample testDObj1 = new sendmailexample(sc2);
        testDObj1.AddRecep='twilms@verisign.conm';
        testDObj1.to ='twilms@verisign.conm';
        testDObj1.EmailCon ='twilms@verisign.conm'; 
        testDObj1.Email ='twilms@verisign.conm';
        testDObj1.body='abc';
        testDObj1.subject='abc';
           
         test.startTest();
         PageReference pageRef = Page.sendmail; // Your page name
         pageRef.getParameters().put('Id', String.valueOf(Contact.Id));
         Test.setCurrentPage(pageRef);
        Test.setMock(HttpCalloutMock.class, new sendmailcontactmock());
          ApexPages.StandardController sc1 = new ApexPages.StandardController(Contact);//Instance of your object
         sendmailexample testDObj = new sendmailexample(sc1);
         testDObj.AddRecep='twilms@verisign.conm';
        testDObj.to ='twilms@verisign.conm';
        testDObj.EmailCon ='twilms@verisign.conm'; 
        testDObj.Email ='twilms@verisign.conm';
        testDObj.body='abc';
        testDObj.subject='abc';
          testDObj.sendpost();        
           test.stopTest();  
            
    }


    
    static testMethod void runTest5(){
  Account account = new Account();
       account.Name = 'Acc3';
       insert account;         

       Contact contact = new Contact();

       contact.AccountID = account.Id;
       contact.Email = 'twilms@verisign.conm';
       contact.MobilePhone = '918527116723';
       insert contact; 
       
        ApexPages.StandardController sc2 = new ApexPages.StandardController(Contact);
        apexpages.currentpage().getparameters().put('ID',contact.id);
        String  conId = ApexPages.currentPage().getParameters().get('Id');
      String  EmailCon =[Select email from Contact where Id=:conId ].email;
      sendmailexample testDObj1 = new sendmailexample(sc2);
        testDObj1.AddRecep='twilms@verisign.conm';
        testDObj1.to ='twilms@verisign.conm';
        testDObj1.EmailCon ='twilms@verisign.conm'; 
        testDObj1.Email ='twilms@verisign.conm';
        testDObj1.body='abc';
         testDObj1.subject='abc';     
            
test.StartTest();
PageReference pageRef = page.sendmail;
Test.setCurrentPage(pageRef);
ApexPages.StandardController sc = new ApexPages.standardController(Contact);
apexpages.currentpage().getparameters().put('Id',contact.id);
sendmailexample testDObj = new sendmailexample(sc);

yes now this error

What is the code in Class  sendmailexample.processSelected: line 138, column 1 ?

Class might be referring some variable in that line, which you have to set in  or pass from test class.

can you plz give me the email ID?

This is the methd for selecting contact list. which stored in wrapper class 
u can check here (part of code)
