How do I make multiple subscriptions on one form? Where people can choose
more then 1 subscriptions?

You will need to configure that on your payment field. Please check this related guide on how to setup subscriptions on your payment field: https://www.jotform.com/help/166-How-to-Setup-a-Recurring-Payment-Option

1. On student learning resource, i would like to add quantity. For example
if some one has 3 students they should be able to do 3 subscription.
2. All these subscriptions should be able to add up to one total. For
example some one can choose to have 3 student learning resource, 1 5th
grade donation and 1 lions den subscription.
3. Also i dont see a check out botton. how do i add that?
4. I would like to have a detailed report of everything sold.
5. Are my jot forms added to PayPal or do i need to call PayPal?
There these things possible to do on Jot forms?
...

Also, i would like to add a section to have parents pay for credit card
fees, is that possible?
Thank you so much,
Rita

I'm afraid that the requirements you're looking for cannot be achieved with the current payment integration options, it's not possible to set up a quantity for subscription or allow to select more than one subscription. 

It's possible to create reports from the submissions data, please kindly check this guide with details about the different reports you can create: https://www.jotform.com/help/326-How-to-Create-Form-Reports-in-JotForm 

Regarding a check out button, due to the payment integration you've used (PayPal Standard) there is no such button, this is the same for almost all the payment integrations as the payment is processed when you submit the form, for the case of PayPal, the user is redirected to the PayPal payment page. 

Since you have already configured PayPal on your form, it's not needed to contact them, your form is currently ready to accept payments. 

Also, i would like to add a section to have parents pay for credit card

fees, is that possible?

The PayPal Standard integration does not allow to pay either using a PayPal account or credit card, but we have other payment integrations that will allow this, here are some guides about this:

I hope this helps.
