Stripe: Are we able to sell products and subscriptions on the same form?

2. I'd like to be able to sell individual products and subscriptions all at once. I would like my customers to be able to purchase multiple products in the same cart - an individual lesson and a subscription. Is this possible?

Unfortunately, it's not possible to use more than one payment type at the same time so you can only sell products or subscriptions. 

There is a workaround on this, here are the guides for that:

I hope this helps.
