Yes.  See 'man bash' for the relevant parameters.

For BL3:  /etc/inittab
For BL2:  /etc/passwd

If your script starts with  #!/bin/bash  it will
look for bash in the /bin directory.

No, sh is the generic name for that family of shells.
/bin/sh usually links to bash or ash or bsh.  And the
scripts usually start with:  #!/bin/sh

No point installing ash.  BL3 already has the full ash.

There are many different shells around, some very small.
One of the smallest is msh (which is used by the loop 
version of BL3 to do the housekeeping necessary to mount 
the loop file).  If you have the loop version of BL3, 
you can execute msh like this:
--------------
/initrd/bin/sh  
--------------
It is not user-friendly -- I removed help to save space.
