You should be able to cancel you individual plans yourself. See: https://helpx.adobe.com/manage-account/using/cancel-subscription.html
However, if it's your colleague who is actually the subscriber with your card details on file, you'll need them to go in to their account and cancel. Or change the payment details with their own. https://helpx.adobe.com/manage-account/using/update-billing-information.html
As mentioned before I want to cancel indesign from my products but the option to cancel indesign subscription is now showing . Even today I have been charged 30 usd and I am paying this for amount for a year without using it . How can I cancel the indesign licence ?

If you PAID FOR a plan belonging to a colleague, you need to get the colleague to cancel it. Regular retail licenses have no owner but the registered user, and businesses have no rights to see invoices, cancel or transfer them, even if the colleague leaves. It is very much not recommended to provide a card to someone else's retail account. Adobe offer team or enterprise plans for business.
Since account is in colleague's name, get in touch with colleague and have them cancel. If they refuse, contact your bank.
If the account is in your name then just contact customer service - no use posting here. If it's in someone else's name you have no right to cancel.
