Passing Multiple Radio buttons value from Visual force page to controller

You can use wrapper class here. This is the best option in your use case. I am adding some sample code taken from Salesforce docs.

public class wrapperClassController { //Our collection of the class/wrapper objects cContact public List<cContact> contactList {get; set;} //This method uses a simple SOQL query to return a List of Contacts public List<cContact> getContacts() { if(contactList == null) { contactList = new List<cContact>(); for(Contact c: [select Id, Name, Email, Phone from Contact limit 10]) { // As each contact is processed we create a new cContact object and add it to the contactList contactList.add(new cContact(c)); } } return contactList; } public PageReference processSelected() { //We create a new list of Contacts that we be populated only with Contacts if they are selected List<Contact> selectedContacts = new List<Contact>(); //We will cycle through our list of cContacts and will check to see if the selected property is set to true, if it is we add the Contact to the selectedContacts list for(cContact cCon: getContacts()) { if(cCon.selected == true) { selectedContacts.add(cCon.con); } } // Now we have our list of selected contacts and can perform any type of logic we want, sending emails, updating a field on the Contact, etc System.debug('These are the selected Contacts...'); for(Contact con: selectedContacts) { system.debug(con); } contactList=null; // we need this line if we performed a write operation because getContacts gets a fresh list now return null; } // This is our wrapper/container class. A container class is a class, a data structure, or an abstract data type whose instances are collections of other objects. In this example a wrapper class contains both the standard salesforce object Contact and a Boolean value public class cContact { public Contact con {get; set;} public Boolean selected {get; set;} //This is the contructor method. When we create a new cContact object we pass a Contact that is set to the con property. We also set the selected value to false public cContact(Contact c) { con = c; selected = false; } } } 

Visual force

<apex:page controller="wrapperClassController"> <apex:form > <apex:pageBlock > <apex:pageBlockButtons > <apex:commandButton value="Process Selected" action="{!processSelected}" rerender="table"/> </apex:pageBlockButtons> <!-- In our table we are displaying the cContact records --> <apex:pageBlockTable value="{!contacts}" var="c" id="table"> <apex:column > <!-- This is our selected Boolean property in our wrapper class --> <apex:inputCheckbox value="{!c.selected}"/> </apex:column> <!-- This is how we access the contact values within our cContact container/wrapper --> <apex:column value="{!c.con.Name}" /> <apex:column value="{!c.con.Email}" /> <apex:column value="{!c.con.Phone}" /> </apex:pageBlockTable> </apex:pageBlock> </apex:form> </apex:page> 

Now use this code as reference you will get all selected value in your code. You can replace the checkbox with inputradio. and it will solve your problem.
