Crypto malware can be responsible for dual (multiple) infections since it will encrypt any directory or file it can read/write to regardless if previously encrypted by another ransomware or variant. Ransomware does not care about the contents of the data or whether your files are already encrypted...it will just re-encrypt (double-encrypt) them again and again if it has access. Even the same ransomware can encrypt data multiple times with different strains which may result in file corruption. That means dealing with all ransomwares, any ransom demand payments and different decryptors in order to decrypt data.
Decreasing your chances for recovering data with dual infections is that files may get corrupted multiple times, especially if the victim tried to use another victim's decryption key, removed the extension or attempted to fix the files by renaming them first. This typically results in more file corruption which complicates possible decryption. Further, using a faulty or incorrect decryptor (one intended for another specific type of ransomware) usually causes additional damage and/or even further corrupts the encrypted files, thus decreasing your chances for recovering data.
Unfortunately there is not much you can do in scenarios like this especially if any of the ransomwares are not decryptable.
