Need to cancel my subscription of these purchase, cause i'm forgot to cancel the in the 24 hours before. Please make it cancel for my purchase application Photogrid, tq.

You must first cancel any subscription automatic renewal (if you simply delete an app this does not cancel subscriptions):

See or cancel your subscriptions [subscription automatic renewal] - "If you signed up for a free or discounted trial subscription and you don't want to renew it, cancel it at least 24 hours before the trial ends." At this stage the renewal is considered a purchase. Canceling a subscription does not automatically start a refund since the existing subscription will normally continue until the end of its term and then just not renew. - https://support.apple.com/HT202039

Apple's terms of purchase in the USA are, "All Transactions are final" (https://www.apple.com/legal/internet-services/itunes/us/terms.html), but some countries have different laws so check terms for your country at: http://www.apple.com/legal/internet-services/itunes/. If sales are final then it is Apple's decision if they want to grant a refund. You can always ask, and people do get refunds on a case by case basis, but Apple can also say no.
