Kindly help me on how to edit Breadcrumbs by changing to another image and uploading video on the home page.

as guided by the screen shorts under position: content_main3

Dear sir,

Please upload your breadcrumb image to inside this folder:
templates/sj_preschool/images/bg/
then go to the file:
/templates/sj_preschool/css/template-yellow.css
and find:
#yt_breadcrumb {
padding: 10% 0;
margin: 0 0 80px;
background: url(../images/bg/bg-breadcrumb.jpg) center center no-repeat;
background-size: cover;
}

Then change bg-breadcrumb.jpg to your file name.
About the video on content_main3, the yt shortcode changed the youtube link to http link (not https), so please send your admin and ftp account in your ticket, we will check it again for you.

Thanks
