Answer 1

No, you can not decrypt/reverse the md5 as it is a one-way hash function till you can not found a extensive vulnerabilities in the MD5. Another way is there are some website has a large amount of set of password database, so you can try online to decode your MD5 or SHA1 hash string. I tried a website like http://www.mycodemyway.com/encrypt-and-decrypt/md5 and its working fine for me but this totally depends on your hash if that hash is stored in that database then you can get the actual string.
