Response time of individual Requests (or sessions) is equal to:
Time to First Byte (TTFB) + Network Time = Time to Last Byte (TTLB)
see - http://support.stresstimulus.com/display/doc50/Request+Details
Response Times for a request can be >= TTFB

A transaction (or a page) comprise of multiple sessions. Some of them are requested in parallel, and some others are requesting sequentially. Transaction response time is an interval between its first session's request and the latest response received (see “Avg. (s)” here http://support.stresstimulus.com/display/doc50/Transaction+Details )

When we are not downloading the static pages in script, Is response time = Connect Time + TTFB ?

Generally, a transaction or a page can have multiple dynamic requests (e.g., a primary page request followed by a dynamic resource returning JSON data), even if you do not download static resources (i.e., static images). Therefore, the transaction (unlike request) does not have TTFB.
If you have a page that has only one dynamic request in no static resources are requested, then such page time will be equal to Connect Time + TTFB + Network time.

When we are downloading the static pages as well: Is response time the total download time or it is the addition of TTFB of main url and TTFB of all static pages?

When a page has multiple requests, then its response is not equal to thy Sum of individual requests’ TTFB because some of the requests can be issued in parallel. Transaction response time is an interval between its first session's request and the latest response received.
