Links from internal pages from other website.

A website link to our site from internal pages of  that site where page rank is 0 but page rank of home page of that website is 5 ,it will helpful or I should get links from a page  where page rank is available there?

Is that page ranking or is that page indexed? Because sometimes can happen you have a link in a page that Google has not indexed (that happens in case of directories, sometimes).

Then, with the Mozbar, check the metrics of that page and of its domain. mozRank value corresponds almost to the real PR of the page and DomainRank and DomainTrust metrics can tell you if it is an authoritative site.

If the metrics are good at least on a domain level, then be happy, because you have obtained naturally a link from a new unique domain name which has good/excellent domain metrics that helps yours domain metrics as well (especially the domainTrust one).

This is the case of being linked in an internal article of the New York Times, for instance.

I would also look at what traffic the other site gets - I like to get links which have a real chance of referring relevant traffic. The websites I work on exist to sell products, so I want links that can attract customers directly as well as indirectly through helping our rankings.

Get both.

PR is not everything, what is more important is page and linktext relevancy

Pursuing the Google toolbar PR is a waste of time. PR is a measure of how popular a page is, not how well it will rank. What good will it do if you have a PR5 page that ranks poorly for keywords?

The question you need to be asking yourself is "What keywords do I want this page to rank well for?"
