Vijay,
Of course you can open your database after creating a new datafile of same. Data of that particular datafile is ever lost.
I guess you mean "ater database create datafile" command right?I don't think that also will work here because that too needs archivelog files to make that new file consistent with rest of the databsae.
Please see here,

As OP is in noarchivelog mode, so I don't think he has this option available.
