if getting the 13 inch MacBook pro, what are the advantages of configuring it with a core i7 chip. And also do Intel iris graphics have dedicated memory?

There is zero advantage of getting an i7 upgrade on the 13", because both dual-core i5s and i7s have 2 cores and 4 threads. Performance difference is almost nil.

Between a quad-core i5 and quad-core i7, the difference can be significant due to hyper threading in the i7 (which is absent in desktop i5s).

And no Mbps have quad cores?

Only 15" have quad-core i7s, with 4 cores and 8 threads (just like desktop i7s).

13" only have dual core i5s and dual core i7s. Both have 2 cores and 4 threads.

Are the 15 inch MacBook pros still portable?

Yes but obviously the 13 inch is more portable.
Yes, it is. I enjoy how small and light-weight my 13" rMBP is compared to the 15" rMBP I used to have.

However, if you need a bigger screen and/or more power the 15" is the obvious way to go.

I got a 15"rMBP + GT750m

It's perfectly portable. I used to have a 17.3 inch Asus laptop which weighed like 4+kg. I have my macbook for half a year now, and when it's in my backpack i still check if i didn't forget it, because it's so light.

If not doing intensive video editing, would you notice a difference in performance?

For light tasks where multi-core performance does not matter, no.
Does watching movies, playing music, multitasking with web browsing, word processing, running GIS, modelling and CAD all count as light tasks?

The base-model 15" would have better CPU performance.

I've used both 13" and 15" and while the 15" is a tad heavier its every bit as portable as the 13" Depending on your usage habits, the 15" is an excellent option.

What about graphics? I'm thinking about whether I should replace this notebook completely or have a portable lower spec device and use the dell notebook for power usage on a desk.

I think you should just get the 15" with dedicated graphics. It is an investment. But it's definitely worth it!
