Can I upload WordPress-react theme in Wp theme repository?

As detailed at https://make.ww.wp.xz.cn/themes/handbook/review/ your theme will need to meet all of the requirements listed at https://make.ww.wp.xz.cn/themes/handbook/review/required/ before it will be included in the theme directory here.

You can certainly start by uploading your theme, and if it makes it past the automated checks, it will then be inspected by a member of the Theme Review Team for everything else. It will only be included in the theme directory here if it is approved by a member of the Theme Review Team, and the theme must meet all of the requirements before it can be approved.
