Editing Text within a Text Widget

How can we edit the text in a text widget?

If you want to bold a name or title or something is this possible?

Is there a limit to how many text widgets we can add to sidebar?

On a previous non-wp site I had testimonials for our newsletter running down sidebar under the optin in form, within a coloured box, with signatures and names in bold and of course neatly spread out.

How can I do this in WP-Atahualpa?

I copied & pasted a lot of testimonals into 1 text box - ghastly to say the least. I then experimented with several text widget each with an individual testim. but realized or couldn't find way to edit.

I also changed colour background for text body of widget in theme option but it only worked on one not on all.

I found the following info in one of Flynn's replies is it something like this that I have to do?

I asked elsewhere (probably wrong place) if we can add Johnson Boxes - i. boxed text areas with different background and with border on a page. Similar in a way to what different posts look like but I can't find how to do this on a page.

once again, looking for answers
