Exactly how you do this is difficult to say, since we have no idea how the rest of your system works. But, this is what I would do:
Create a storage medium that holds questions and answers: this could be a database, xml file, spreadsheet, or even a text file. Basically anything you are happy with that you can retrieve data from.
Each question would have a question text ("What colour is a ball?") and right answer ("White") and a number of wrong answers - this could be two, or you could have more and randomly select two of them.
Then, for each question, I'd use the Random class to give me a number and put the right answer in that radioButton.Text field - and set the Tag field of the control to "true". The other two radio buttons would get wrong answers, and a Tag of false.
When the button is pressed, find the selected radio button, and check it's Tag - if it's true they got it right.

Simple!
   
There are many possible ways of implementation you could use here, and OriginalGriff has given you excellent suggestions.

A key question is: what is your goal here ? To create a one-off solution where all the logic and events happen in one Windows Form ? Or, to create a general solution that you can re-use in other projects, and to which you can add new features (extensibility) ?

Specific suggestions, whether your goal is one-off, or re-usable: don't use a separate Form for each question:

1. use a single Panel, or other ContainerControl, to hold the RadioButtons and other Controls you need, and re-use those Controls, changing their content for each question.

2. if you had additional content unique to each question (a picture ?), you could consider using a TabControl, with unique content for each question on each TabPage.

3. fyi: an alternative to checking one RadioButton at random is to set the Checked value of all RadioButtons to 'false at the start of each question. this may avoid a slight unconscious bias of the person taking the test to consider the checked value as being, possibly, more likely to be correct.

4. if your goal is a re-usable solution, consider using classes, to "model" both the collection of Questions/Answers, and individual Question/Answers. ask for help here with that, if you wish.
   
Hello,
When user selects the answer and hits next button check for correct answer, if it is correct add a count to session and open next form, in next forms increment count if answer is correct.
   
1)instead of 5 forms you can change the text of the radiobutton and maintain a flag which question is to be shown.

2)to check how many correct answer declare 2 public variable and assign value on checked change of radio button.
