Form customization

Hi, just saw the tipping form option where a user enters: amount dropdown, recurring or not, then pay button.

Firstly, can I use PayPal with tis tipping form?

Secondly, if I create a website and use this form, I obviously enter my PayPal account details. But, what if I would like members on my website to receive donations? So lets say I have 50 members, each member has his own profile page. I would like to add this form on each members profile page so that users can then tip/support this member.
When members sign up on my website they already have to enter their own PayPal account details, so is there a way to pull that information into the tip button?

For this form to work in the way intended by me I see currently 2 ways to go:

1: I enter each members PayPal email manually into the button or
2: the tip button can pull the email info from the members profile

Could you pls let me know if this is possible? I am looking for a “tip this creator”, “support this creator”kind of solution.
Any suggestions are welcome ??
