Hi @Niti-and-Ashwani0
Good questions! Regarding hosting experience, im sorry to disappoint but im not knowledgeable about experience since im not hosting an experience. I would suggest you contact airbnb about that or reach out other wider thread to check other experience hosts.
With regards to verification, you can upload two different photos as long as the photos are your real picturez. And u will have to do verification in each account separately. There is no way for airbnb to merge two accounts so if both of u are going to host one of u will be the primary host and the other one will be a co-host.
I strongly suggest you reach out Airbnb to guide you set up ur experience hosting account.
Have a great day!
