<apex:page controller="mensajeController"  >
<apex:form >
 <apex:pageBlock >
 <apex:pageBlockButtons >
   <apex:commandButton value="Process Selected" action="{!processSelected}" rerender="test"/>
  </apex:pageBlockButtons>
  <apex:pageBlockTable value="{!contacts}" var="c" >
   <apex:column >
    <apex:inputCheckbox value="{!c.selected}"/>
   </apex:column>
    <apex:column value="{!c.con.Name}" />
    <apex:column value="{!c.con.Email}" />
    <apex:column value="{!c.con.Phone}" />
  </apex:pageBlockTable>
 </apex:pageBlock>
    <apex:pageBlock>
        <p>Current description: {!mensajeContenido}</p>
        <p>Change description to:</p> 
        <apex:inputTextarea id="newDesc" value="{!mensajeContenido}"/><p/>
        <apex:commandButton value="Save" action="{!save}"/>
    </apex:pageBlock>
 <apex:pageBlock id="test">
  Total No of Selected Records :<apex:outputText value="{!value }"/>
  <apex:pageBlockTable value="{!SelectedContacts}" var="c" >
    <apex:column value="{!c.Name}" />
    <apex:column value="{!c.Email}" />
    <apex:column value="{!c.Phone}" />
  </apex:pageBlockTable>
 </apex:pageBlock>
 </apex:form>
</apex:page>

this is the controller

public class mensajeController {
    public List<cContact> contactList {get; set;}
    public List<Contact> selectedContacts{get;set;}
    public Integer value {get;set;}
    public List<cContact> getContacts() {
        if(contactList == null) {
            contactList = new List<cContact>();
            for(Contact c : [select Id, Name, Email, Phone from Contact]) {
            contactList.add(new cContact(c));
            }
        }
    return contactList;
}
public PageReference processSelected() {
    selectedContacts = new List<Contact>();
    for(cContact cCon : getContacts()) {
        if(cCon.selected == true) {
        selectedContacts.add(cCon.con);
        }
    }
    value = selectedContacts.size();
    System.debug('printingtcontc'+selectedContacts.size());
    return null;
}
public List<Contact> getSelectedContacts(){
    System.debug('printingtcontc inside get'+selectedContacts.size());
    if(selectedContacts.size()>0)
       return selectedContacts;
    else return null;
}
public class cContact {
    public Contact con {get; set;}
    public Boolean selected {get; set;}
    public cContact(Contact c) {
    con = c;
    selected = false;
    }
}
    public class messageDescription {
        public string mensajeContenido {get; set;}
    }
}

hi  Rafael,
you can not reference wrapper class method with vf page. you can create a variable and the directly use it.
public class mensajeController {
    public List<cContact> contactList {get; set;}
    public List<Contact> selectedContacts{get;set;}
    public string oMessageDescription{get;set;}
    public Integer value {get;set;}
    public List<cContact> getContacts() {
        if(contactList == null) {
            contactList = new List<cContact>();
            for(Contact c : [select Id, Name, Email, Phone from Contact]) {
            contactList.add(new cContact(c));
            }
        }
    return contactList;
}
    public  PageReference save(){
        system.debug('test===> ');
        return null;
    } 
public PageReference processSelected() {
    selectedContacts = new List<Contact>();
