Hello
If your first form is completed fine and you also need the second form same as first, its very simple just use the same classes or ids for it.
For example, if you want to style Submit button use this
.wpcf7-submit
Its default class for contact form 7 submit button, you can use any style here or you can also use it in this type
.wpcf7 .wpcf7-submit
Thank you
