Re: "But there is these other subscriptions on there" : "it doesn’t say cancel subscription at all".
Seems like you may need to cancel some old subscriptions, that would be up to you:
What to do: If you want to cancel a subscription from Apple – Apple Support
If the subscriptions have not been cancelled, then Apple would likely be expecting payment, sooner or later.
If payment for active subscriptions was not possible, then Apple would likely charge your card as soon as possible and renew the subscriptions.

Re: "tells me to put in my card information and so I did and it still doesn’t let me reinstall my app".
If you have debated a charge from Apple, then you may need to authorise your card-provider to allow payments to Apple again.

If you wish you can log-in to your account online and check it is up-to-date:
