hi punediary using multiple anchor texts in back links means that you use different keywords as anchor texts to point to same URL. Using multiple anchor text naturally also help you avoiding the spam filter of search engines. You can use variety of keywords as anchor text while back linking process( but be sure that whole  process of back linking looks natural).  Yes you should bookmark pages of your website other than homepage, there is no harm...
ok...then 1 more question is that keywords which is used in anchor text is necessary to match with that page or related to that site?
it doesn't look natural to have two links to the same site with different anchor text right next to each other. When you are looking for long term rankings you should be aiming for a link profile that is as natural as possible.
Well, anchor text is the visible characters and words that hyperlink display when linking to another document or location on the web. Link relevancy is determined by both the content of the source page and the content of the anchor text.
When SEO’s Link build they concentrate time and power on one term, this could in time become a mistake. Links like these are very easy to track, if they are all the same they are usually being created by the same person (although this may not apply to Brand names, but that is a different matter). Using different terms suggests that others could be linking to your website (just as many people would normally link to your site using the standard URL format).
Use Multiple Anchor Texts: As mentioned before, you should be using your main keywords in your anchor texts. Make sure you vary them a little bit. Pick 3-5 of your primary phrases and use them all as anchor text on different sites. Having too many of the exact phrases pointing to your site might raise a red flag over at Google and they may even penalize your site. So use a lot of variations and different key phrases in your anchor text.
