In brief: Yes

I would argue that a 5-6 won't be innocent.
Innocent murmurs are more common than pathological ones. Yours may not have been innocent but been mild disease, like a mildly narrowed (stenotic) valve. It could slowly progress and the murmur would become louder or harsher over time. If its a 5, you should probably have an echocardiogram.

In brief: Possible

There are a lots of reasons for cardiac murmurs.
All grade 4-6 murmurs must be considered pathological and needs to be checked out. Usually innocent murmur does not change to become grade 4 or above. Murmurs that are progressive need to have some structural abnormality and by definition innocent murmur does not have structural abnormality.
