No, but canonical understanding says yes (so it would depend on what level the class you're working on). This gets really complicated really fast, so you'd best just check out the link to a recent article from molecular biology of the cell concerning an alternate binding site should all others be occupied by non-translating ribosomes, if you're truly interested. Hope this helps.

yes...the ribosome does not attach to the ER until after it gets the mRNA and starts translating.
There is a signal sequence that is recognized by....the signal recognition partical...which binds the ribosome to the Sec 61 complex in the ER. The ribosome then translates the message...some of the protein ends up in the lumen of the ER...some of it in the cytosol and some of it in trans-membrane domains.
Pretty sure the ribosome falls off after translation stops.

Yes, because the only reason the ribosome binds to the endoplasmic reticulum is to directly insert certain proteins into it.

Yes
The answer is allways Yes, unless it is No, then the answer is No, but in this case it is Yes.
