Hello Aspirant,
See your documents stored in Digiloker is only for online use and it cannot be used in a hard copy as it is digitally signed and it will be valid for only online purpose. Admission cannot be made permanently on the basis of these documents but yes as you have lost them so you should arrange the new ones as soon as possible bu till than you can talk to the competent authorities and inform them about your issue and they will surely help you.
So you can get some time from that documents but you have to arrange the original documents as soon as possible. Note that IIM Indore has started the applications for CAT 2020 and this process will continues till September 16th so you have only few days left, if you can arrange the documents in this period it is fine but yes if you could not get that by the time so you can take some time using these online/digitally signed documents.
