Sounds like guides are locked
Such a simple thing. You're right. Thank you!!
so guess what, I have found a few files that are behaving the way that prompted me to write. The guides are all unlocked, and there are none on the master pages, but still will not delete. Here are some screengrabs of me checking the master pages and trying to delete the guides. I can provide the indd file if anyone wants to see it. I'm so perplexed. I have two other examples, too.
Ruler Guides are layer wide , means they are dependent on the layer they were created that's why when you select the Ruler guides they get highlighted with the layer color.
The Reason of Ruler Guide not getting selected could be :-
1) Guides are locked (View-->Grids and Guides-->lock Guides)
2) Guides created on the Master pages and we are trying to access it on the Document page
3) Guides created on a particular layer and in the layers property you have the "lock Guide" option checked. (Right click on the Layer in the Layer panel , go to Layer options , uncheck Lock Guide)
4) Guides created on particular layer and the layer itself is locked.
So, as per the screen shot you provided , either the layer is locked or in the layers options you have the "Lock Guide" option checked.

Take a close look at the Pages panel. Do you see the 1-Up notation in the top of the Page 1 Thumbnail? That means the page is based on the 1-Up Master. You're looking on the wrong master page for the guides.
The master you want isn't currently showing in the panel, and there may be others there as well. You need to scroll down through them in the master section (see the scroll bar along the side of the master pages pane? That's only there when there's more to see).
Thank you! You're right I wasn't looking at all of the masters.
There are two type of guide in indesign.
First one is, as generally used, just GUIDE. This guide is created in the Layout > Create guides, and so on....
Second one is, I think this may be the main reason of many questions which saying "cann't delete guide!", DOCUMENT COLUMN GUIDE. This guide is created when you first initialize your document or you can setup this in the Layout > margin and columns. The minimum value is 1, because the whole page itself is a column.
So, when you struck in problem with guides, please check the document column guide number. If you wanna make your page clear, setup that value as 1.
JFYI, when you go to the View > Grid & Guides, there are two guide view options. "Lock guides" and "Lock column guides" As I already mentioned, this lock options is for the each type of guide.
