Are you aware that using only upper case letters is considered SHOUTING?

You can use rectangle() to plot the circle and oval.

You can use text() to place text labels on the plot.

Kristen, you just had to modify the examples in the help, like this:

% Initialization steps.
clc;    % Clear the command window.
close all;  % Close all figures (except those of imtool.)
clear;  % Erase all existing variables. Or clearvars if you want.
workspace;  % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 13;
% Define oscillation parameters.
period = 10;
t = linspace(0, 5 * pi, 100);
y = 30 * sin(2 * pi * t / period);
% Define graphics parameters:
rectangleHeight = 0.15;
rectangleWidth = 0.15;
rectangleLowerLeftX1 = 0.0;
rectangleLowerLeftY1 = 0.1;
lineX = 15;
% Set up axes.
grid on;
ylim([-0.150, 0.3]);
xlim([-0.15, 0.25]);
xlabel('X', 'FontSize', 15);
ylabel('Y', 'FontSize', 15);
faceColor = [.95, 1, .95];
axis('equal');
% Start the movement:
% Place a rectangle at the current y location.
r = rectangle('Position', [rectangleLowerLeftX1, rectangleLowerLeftY1, rectangleWidth, rectangleHeight], ...
	'Curvature', [1, 1], ...
	'LineWidth', 3, ...
	'EdgeColor', 'b', ...
	'FaceColor', faceColor);
title('Rectangles and circles and ovals', 'FontSize', 15);
% Do the oval
rectangleHeight = 0.09 * 2;
rectangleWidth = 1.07;
rectangleLowerLeftX1 = -1;
rectangleLowerLeftY1 = -0.09;
r = rectangle('Position', [rectangleLowerLeftX1, rectangleLowerLeftY1, rectangleWidth, rectangleHeight], ...
	'Curvature', 1, ...
	'LineWidth', 3, ...
	'EdgeColor', 'b', ...
	'FaceColor', faceColor);
xlim([-0.15, 0.25]);

This looks pretty close to the figure you posted. Adapt parameters as needed.

@Image AnalystI DIDN'T UNDERSTAND CAN YOU PLEASE EXPLAIN IT IN MORE DETAILS?

@Kristen Chappel

In order to plot more than one point on a plot you need to provide more than one data point. You have not explained where the data for 'Line 1' and 'Line 2' is coming from. As soon as you figure out where that data is coming from it will be easy to plot it along with the other shapes that Image Analyst showed you how to plot.

You should not really post repeated requests for help (especially in all caps, please turn off your caps lock, it is usually interpreted as "yelling") when you haven't explained what you really want or, apparently, listened to the previously provided suggestions..

Explain how you want to "ENTER THE VALUE OF X AND Y MANUALLY ACCORDING TO OUR CHOICE". As Image Analyst suggested, you could prompt for them on the command line (using input()) or create a dialog to ask for the values (using inputdlg()). Or, if you want to do it by clicking on the figure you could try ginput().

Read the documentation for those functions. Here are links to the online docs: input, inputdlg, ginput.

Read the examples and come back with specific questions when you have tried something and it didn't work. Also, post the code that isn't working and show any error messages that you get (the complete error message) and explain what you expect and why what you get isn't what you want.
