How to pass get images in homepage also in portfolio page?

You’re saying that you’ve set images in homepage admin, so I guess you’re using static page as homepage… In such case you can use this code to show these images anywhere else on your site:

<div class="container">
    <div class="journal-block">
        <div class="row">

            <?php if ( have_rows( 'gaimages', get_option('page_on_front') ) ): ?>

                <?php
                    while ( have_rows( 'gaimages', get_option('page_on_front') ) ) :
                        the_row(); 
                        $image = get_sub_field('images');
                        $text = get_sub_field('text12');
                        $text11 = "Hai Tst";
                ?>
                <div class="col-lg-4 col-md-6">
                    <div class="journal-info">
                        <a href="https://wordpress.stackexchange.com/questions/305657/blog-single.html">
                            <img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt'] ?>">
                        </a>

                        <div class="journal-txt">
                            <h4><a href="https://wordpress.stackexchange.com/questions/305657/blog-single.html">
                                <?php echo $text; ?>
                            </a></h4>
                            <p class="separator">To an English person, it will seem like simplified English</p>

                        </div>

                    </div>
                </div>
                <?php endwhile; ?>

            <?php endif; ?>

        </div>
    </div>
</div>
