Hello,
Toolset repeatable field group is based on one-to-many relationship, each item of repeatable field group is also a single post, so you will need to follow our document to setup another form for user to add new item in repeatable field groups:
https://toolset.com/documentation/post-relationships/selecting-parent-posts-using-forms-create-child-items/
According to W3C document, you can not embed one HTML form(child post form) into another HTML form(parent post form), see similar thread:
https://stackoverflow.com/questions/379610/can-you-nest-html-forms
And in your case, it needs only a custom multiple-instances image field, in the form for creating post, you can enable option "Use the WordPress Media Library manager for image, video, audio, or file fields", see our document:
https://toolset.com/documentation/user-guides/front-end-forms/using-the-native-wordpress-media-manager-in-front-end-forms/
When user upload an image, he canupload multiple images in the same image field, and setup the image attributes, including "capiton", see screenshot Caption.JPG.
The Toolset Gallery block will display image caption text at the bottom of each image, see screenshot captions.JPG
More help:

And you can also follow our document to display the image attributes(caption, title, alt) with Types shortcode, see our document:
https://toolset.com/documentation/customizing-sites-using-php/functions/#image
For the alt and title attributes, you can also use placeholders to output the values of standard image fields added in WordPress: %%TITLE%%, %%ALT%%, %%CAPTION %%, and %%DESCRIPTION%%.
In the gallery there is the option to display captions from the media item.
There is no such thing with an image.
